AZ2: A survey on context aware participant selection for mobile crowdsensing

Tutor:  Aziza Zhanabatyrova (zhanabatyrova.aziza@aalto.fi)

One of the challenges is to select a minimal set of participants from a large crowd of users that perform data collection to provide a sufficient coverage while avoiding unnecessary resource consumption. The context of participants may describe the participant’s status(running, walking, etc) and the surrounding environment (park, home, etc) and can help to match participants more precisely. In this survey, we are interested in various sensor data describing the context, especially visual sensors.

AZ3: Challenges behind large scale Structure from Motion Mapping

Tutor:  Aziza Zhanabatyrova (zhanabatyrova.aziza@aalto.fi)

Structure from Motion achieves a great success in 3D reconstruction. However, this method still faces challenges on a larger (city) scale. In this task a student should make a survey on papers that discuss or address such challenges. We are especially interested in urban (street-view) mapping.

AB: Likelihood-free model selection

Tutor: Ayush Bharti (ayush.bharti@aalto.fi)

Model selection or comparison entails picking the best fitting model from a set of candidate models. This process involves inferring parameters of the given models based on data via the likelihood function. However, for many models in engineering and physical sciences domains, the likelihood function is unavailable. Many methods have been proposed in the literature to address this issue. In this project, you will review the existing literature on likelihood-free model selection methods.

AM: Machine learning the dynamics of noisy qubits

Tutor: Arshpreet Maan (arshpreet.maan@aalto.fi)

Classical neural networks have been shown to be capable of learning the dynamics of quantum systems[1]. One such quantum system is a quantum computer. However, errors are easily induced in quantum computations due to the computer’s interaction with the environment. The purpose of this project is to perform the literature review on machine learning the dynamics of qubits (quantum bits)[2] under the influence of the environment using open quantum system simulation software [3].

AP: Quantum Natural Language Processing (Customized topic, do not select)

Tutor: Alexandru Paler (alexandru.paler@aalto.fi)

Student: Ioana Moflic

The goal of the project is to look into the training of a quantum neural network to generate (country) songs. Initial quantum natural language processing results were generated with the ZX calculus (see references). The literature is quite sparse and it would be very helpful to review classical natural language processing and check which concepts are practically translatable into the quantum real, where practicality is related to the architecture of the models, the performance of the quantum circuit simulators (e.g. in PennyLane) and the size of the data to be learned.

AY1: Microservices - when and how to use them

Tutor: Antti Ylä-Jääski (antti.yla-jaaski@aalto.fi)

Microservice architecture is a modern approach to software system design in which the functionality of the system is divided into small independent units. Microservice systems differ from a more traditional monolithic system in many ways some of which are unexpected. A cost of a migration from a monolithic system to a system based on microservices is often substantial so this decision needs to be carefully evaluated. Microservices have become very popular in recent years. An increasing number of companies (e.g., Amazon, Netflix, LinkedIn) are moving towards dismantling their existing monolithic applications in favor of distributed microservice systems. As with any big software project, migrating to a microservice architecture often requires considerable investment. In this project work, you will discuss the benefits and drawbacks of adopting microservice architecture in comparison to monolithic architecture. Depending on your interests, possible viewpoints to this generic topic are also for example security challenges, scalability, serverless computing, service mesh, big data platforms, etc.

AY2: Energy saving capabilities of Kubernetes

Tutor: Antti Ylä-Jääski (antti.yla-jaaski@aalto.fi)

Cloud computing provides unparalleled benefits of efficiency, flexibility, and cost savings.  It has enabled new business models like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) that leverage ubiquitous access to data center facilities. According to a 2019 report of the International Energy Agency, data centers consume approximately 200 TWh of electricity, or nearly 1% of global electricity demand [1]. It is expected that the energy consumption of data centers will rise to 2967 TWh in 2030 which further increases CO2 emissions [2]. The energy use of mobile operators is distributed between radio, core, and back-office data centers so that more than 73% of energy is consumed in the radio network. However, due to the transition of radio network into the cloud (through virtualization and cloudification of the RAN elements), the energy efficiency of the cloud computing becomes stressed.      

Kubernetes container management system has become the de-facto means to manage virtualized workloads.  Kubernetes provides significant improvements in server utilization through scheduling workloads to servers matching the computational need staking into account performance and energy efficiency tradeoffs and power usage effectiveness. The purpose of the study is to survey the recent extensions for Kubernetes to address energy efficiency through workload scheduling and server consolidation [3,4,5,6,7]. The survey tries to answer what are the methods for creating energy efficient Kubernetes deployments, what is assumed from the underlying server infrastructure and CPUs, what are the promising workload scheduling and load balancing approaches and metrics they use.

AR: Algorithmic power

Tutor: Antti Rannisto (Antti.rannisto@aalto.fi)

Algorithms are increasingly placed in positions holding social agency. This redistribution of agency is related to important questions of societal power. Who decides who decides - and based on which ideologies and interests. Technology is not neutral, and thus it is important to inspect questions of power especially related to so-called autonomous technologies like algorithmic systems.

AL: Authentication, authorization, and session management for web applications

Tutor: aleksi.peltonen@aalto.fi

The goal of this topic is to investigate the security of modern technologies for authentication, authorization, and session management. Relevant topics include, but are not limited to, client authorization (e.g., OAuth 2.0 [1]), access tokens (e.g., OAuth Bearer Tokens [2], JSON Web Tokens (JWT) [3]), and user authentication (e.g., OpenId Connect [4]). Each student will choose one of the above-mentioned technologies or suggest a topic of their own. Prior knowledge of relevant technologies is required for selecting this topic. Students chosen for the topic are expected to conduct independent experiments and a comprehensive literature review of relevant security papers. In particular, students should familiarize themselves with research literature concerning formal verification (e.g., [5, 6]) of the chosen technologies.

AS1: Speaker recognition

Tutor: Abduljalil Saif (abduljalil.saif@aalto.fi)

Active speaker detection/recognition has become one of the promising methods for speech and video scene understanding. Deep learning-based techniques are widely used for active speaker detection and recogntion. The student needs to write a survey paper under one of these two topics, and run few codes pertaining to the reviewed papers. These two projects should be done separately where the "speaker recognition" topic can be hands on with a technical paper, while "active speaker detection" topic can be a survey and hands on.

SS1: Security indicators and warnings

Tutor: Sanna Suoranta (sanna.suoranta@aalto.fi)

Many software warns the user with a dialogue when something unexpected happens. However, people often ignore all the warnings and just click the OK button to get rid of those dialogues. The reason is not necessarily indifference or negligence but the way how human brain habituates stumuli that are often seen. Furhtermore, researchers can investigate areas of web services where users look with eye tracking. Users do not often look security indicators but just the content of a service page. The aim of this work is to investigate what researchers have suggested as solutions for the problem of noticing security issues that they encounter while using web services.

SS2: Usability of passwords

Tutor: Sanna Suoranta (sanna.suoranta@aalto.fi)

Passwords are known to all who use any digital services. Many other means have been suggested for authentication but we still use passwords. For example, if automatically generated strong passwords are such that they can be pronounced, they are easier to remember. Furthermore, mobile devices have created new problems for typing in passwords. The aim of this work is to investigate how usability of passwords can be improved.

SS3: Psychometry for researching usable security

Tutor: Sanna Suoranta (sanna.suoranta@aalto.fi)

Instead of just asking from users, the development of psychometric tools have given ways to really see how users react to software. For example, a decrease in the amplitude of the peripheral vascular pulse indicates mental stress, and it can be detected with photoplethysmogram. There is increasing amount of research where these tools are used in improving usability of software, but how about usability of security? The aim of this work is to investigate how psychometry is used in research of usable security.

Tutor: Linh Truong (linh.truong@aalto.fi)

The topic will research how current techniques and tools support the developer and/or the provider to debug, log and monitor components/services/tasks in ML systems in distributed computing infrastructures. The research should highlight differences (and challenges) of debugging, logging and monitoring for ML systems. The topic is for a single student. We recommend it for students with some experiences in cloud software and systems. We expect the student to present a viewpoint in the topic, thus scoping the research to target a specific type of audience, and presents the result providing useful information to the audience.

YV: Molecular Representation learning

Tutor: Yogesh Verma (yogesh.verma@aalto.fi)

Molecular representation learning aims to learn the representation of molecules that captures their inherent chemical properties and relationships. This representation is then used to predict various molecular properties, such as biological activity or solubility, or to perform tasks such as virtual screening or drug design. The goal of molecular representation learning is to enable the use of machine learning for tasks in chemistry and drug discovery and to improve our understanding of the relationships between molecular structure and function. In this project, you will review the existing literature on representation learning applied to molecules and explore their shortcomings and experiment with new representation learning methodologies. A chemistry and biology background is not a mandatory requirement for the project.

TA: Network virtualization today

Tutor: Tuomas Aura (tuomas.aura@aalto.fi)

Computer networks are no longer just physical devices connected with cables. Instead, they can be multilayered virtual networks that are implemented in software or software-controlled networks built on top of the underlying physical infrastructure. The goal of this topic is to investigate the state of the art in virtual computer networks from many different points of view such as: • Kubernetes cluster network model and its limitations • Docker container networking model and its limitations • Container network interface (CNI) implementations • Virtual network models in commercial cloud platforms (Amazon, Google, Azure) • IPv6 in Kubernetes cluster networks • Kubernetes network policies and deploying them with Helm • Service mesh technical details • Zero trust network security model in cloud networks (focus on technical implementation) • Linux Containers network stack • Connecting on-site and virtual cloud networks Students can also suggest other angles to virtual networking. For example, it is possible to take a fresh look at software-defined networks (SDN), network function virtualization (NFV), and even older technologies VLANs and VXLAN. The paper can focus on the logical networking model and its applications, or it can include a longer discussion of security and isolation. Each student will choose one virtual network technology or model. They must have some prior knowledge of the relevant technologies (e.g., TCP/IP, Docker, Kubernetes, Linux containers) so that they can dive deep into the literature and technical documentation of the specific networking topic. The student must be able to conduct independent experiments to create examples for the paper. This topic can be chosen by multiple students, and it is possible for two students to co-author the seminar paper. The first tutoring rounds will be conducted as group meetings. When co-authoring, it is important that the students conduct the research and writing together to produce slightly more ambitious results.

TN: SLA management for Machine Learning Inference across Cloud-Edge environment: Challenges and Opportunities

Tutor: Tri Nguyen (tri.m.nguyen@aalto.fi)

The widespread across many domains of ML presents many opportunities for ML providers offering inference services such as object recognition, personal assistant, virus detection, etc. Like other cloud services, ML inference services must also be managed under Service Level Agreements (SLAs) which involve multiple stakeholders including ML users, ML providers, Infrastructure providers, etc. Assume that the ML provider deploys many different trained models across heterogeneous cloud-edge infrastructures. They offer ML inference services following the ensemble learning model and serve various ML users (multi-tenancy). Does the current support for SLAs in ML serving fulfill all stakeholder expectations? What aspects/metrics are still missing in SLAs, and what are the challenges and opportunities in SLAs management for ML inference services? This topic can be done by single/multiple students, and individual/group work.

SC: Modern applications of software reliability growth models

Tutor: Stanislav Chren (stanislav.chren@aalto.fi)

Developing reliable software is a challenging task. Software reliability growth models (SRGMs) are one of the oldest and most widely applied black-box reliability prediction approaches that can aid with the reliability evaluation and release planning of software products. Many traditional SRGMs have been proposed with legacy software development practices in mind, such as the Waterfall development process. This results in model assumptions that are likely to be violated in open-source software products and agile environments. The goal of this seminar topic is to investigate more recent SRGM approaches to understand their applicability in modern contexts. The work will focus on a literature review and comparison of SRGM parameters, their assumptions and limitations.

SL: Blockchains and Proof-of-X protocols: security vulnerabilities and tradeoffs

Tutor: Shushu Liu (shushu.liu@nokia-bell-labs.com)

Blockchains and the distributed ledger technology (DLT) underlying them are the foundation for Web 3.0, cryptocurrencies and cryptonetworks, and – more generally – for ensuring trusted tamperproof transactions among untrusted and semi-trusted entities. Such transactions are ensured by DLTs via distributed consensus protocols, such as Proof-of-Work and Proof-of-Stake. However, such distributed consensus protocols present tradeoffs between costs (e.g. high energy usage for Proof-of-Work) and potential security vulnerabilities. More generally, a variety of such Proof-of-X protocols are emerging in Web 3.0. We propose a survey that addresses the following questions: • What are key Proof-of-X protocols for established and emerging blockchains/DLTs? • What are the kinds of security vulnerabilities intrinsic to each of these Proof-of-X protocols? • What are the “costs” associated with each of these Proof-of-X protocols and the tradeoffs with security? • For which kinds of applications are each of these Proof-of-X protocols best suited, given the security vulnerabilities and cost tradeoffs?

SD: Deep reinforcement learning for Human-AI cooperation

Tutor: Sebastiaan De Peuter (sebastiaan.depeuter@aalto.fi)

A fundamental challenge of AI is to create agents that can cooperate with humans. Advances in reinforcement learning (RL) allow us to train agents to be cooperative, but we need a model of a human to train them against. Due to a lack of training data, historically we have had to either hand-craft such models, or use another (optimal!) RL agent as human model. Computational rationality, a recent development in cognitive science, allows us to use deep RL to produce human-like behavior without any human data. These ‘synthetic humans’ can learn to act within an environment and to interact with other (AI) agents, while reproducing hallmark biases of real human behavior. In this project you will implement and train such a SOTA ‘synthetic human’ for a specific decision making task. You will then combine this ‘synthetic human’ with an AI agent into a multi-agent setting and train both to cooperate. Experience with python and knowledge of RL is mandatory. Experience with PyTorch or stable-baselines is recommended.

RL: Succinct Non-Interactive Arguments

Tutor: Russell W. F. Lai (russell.lai@aalto.fi)

A prover P wants to convince a verifier V that a certain mathematical statement is true. Additionally, the task should be completed in the following fashion: Complete: If the statement is true, V should be convinced. Knowledge-sound: If V is convinced, P must know that the statement is true. Non-interactive: It suffices for P to send a single message, called the proof, to V. Succinct: The proof is short, much shorter than the statement. An argument system that accomplishes the above is called a succinct non-interactive argument of knowledge (SNARK). An on-going research direction is to construct SNARKs with different efficiency and security trade-offs and from different computational assumptions. One major direction is to first construct a probabilistically checkable proof (PCP) or its generalisation, then then turn it into a SNARK using a cryptographic compiler. Students are tasked to survey this area of research, summarise known results, and identify open problems. Mathematical maturity is required for this topic.

RW: Dynamics of social interactions in social Mixed Reality

Tutor: Robin Welsch (robin.welsch@aalto.fi)

To initiate social interaction with a stranger, we put a smile on our face, move closer and seek eye contact. Only after being recognized, e.g., by mimicking the smile, a verbal conversation is initiated, accompanied by a reduction of interpersonal distance. Using Mixed reality as an innovative method, researchers can simulate social interactions in a highly controlled, highly economical, but also ecologically valid way. Here, novel methodological developments of Mixed Reality technology now enable us to granularly study social interaction and its dynamics in high fidelity virtualized environments. The goal of this project is to grasp state-of-the simulations of dynamic nonverbal-behavior within Mixed reality.

NS: Virtual reality toward the internet of senses

Tutor: Nassim Sehad (nassim.sehad@aalto.fi)

The emergence of 5th-generation networks and the introduction of the ultra-low latency Internet, namely, tactile internet, by the International Telecommunication Union (ITU) has opened up a wide range of applications. Extended Reality (XR), holoportation, and remote control of machines are among the ones that would revolutionize the future of factories, smart cities, and digital healthcare. To enable a high sense of immersion and embodiment in virtual environments, Virtual Reality (VR) technology provides users highly realistic visual and auditory experiences. In the real world, however, we use more senses than only vision and hearing to perceive our surroundings. Particularly, tactile sensation is the only bidirectional modality and enables us to perceive and interact with the objects and surfaces around us. The Internet of Senses (IoS) aims at transforming the digital world into a fully immersive one by delivering over the network multisensory experiences including visual, audio, haptic, smell and taste. This consists of two requirements. One is the user interfaces such as haptic devices which would allow users to receive tactile information through sensations. The other is networking technologies that would enable ultra-low latency delivery and synchronization of multisensory experiences. We refer to it as multiple sensorial media (Mulsemedia) in the rest of this proposal. So far, the development of haptic interfaces is still in its infancy, while advancement in networking technologies is needed to enable multiple sensorial media.

MD1: Multi-factor authentication with mobile devices: open challenges

Tutor: Mario Di Francesco (mario.di.francesco@aalto.fi)

Multi-factor authentication (MFA) involves using at least two different means for user verification. It is widely used by online services, especially those which are cloud-based. A common option for MFA leverages a password and a second factor provided through a mobile device, for instance, a time-based token. Despite being widely used, MFA does not solve the issue of secure authentication and has several challenges, also related to usability. The focus of this seminar topic is to explore different options for MFA involving mobile devices then to evaluate their security and usability.

MD2: Security and privacy in the metaverse

Tutor: Mario Di Francesco (mario.di.francesco@aalto.fi)

The metaverse represents the social aspects of virtual and augmented reality. Security and privacy have been thoroughly investigated for conventional scenarios; in contrast, they have received limited consideration in the context of the metaverse. The focus of this seminar topic is to address this gap by overviewing the issues related to security and privacy in the metaverse.

MD3: Deep neural network compression for resource-constrained devices

Tutor: Mario Di Francesco (mario.di.francesco@aalto.fi)

Large Deep Neural Networks (DNNs) with billions of parameters are becoming increasingly popular to solve many important problems, though their deployment in resource-constrained devices still remains a challenge. Several DNN model compression approaches have been proposed to tackle this problem including pruning, quantization, and knowledge distillation. The focus of this seminar topic is to review approaches for DNN compression and select one option to consider in more detail.

MK: Using and optimizing stencil applications for GPUs using a CUDA-MPI library Astaroth

Tutor: Maarit Korpi-Lagg (maarit.korpi-lagg@aalto.fi)

In the TOP500 list of supercomputers, roughly 30 percent are currently based on accelerator platforms, such as graphics processing units. As the clocking frequency of the CPUs can no longer be increased to perform computations faster due to the power wall phenomenon, the emphasis has changed to maximising throughput using devices capable of massive parallelism. In this project, you will learn to use, optimise (communication versus computation), compare performance on hardware from different vendors, and measure the energy-efficiency of a standard stencil-based application implemented with a CUDA-library Astaroth.

JM: Learning Biological ODE models from time series data

Tutor: Julien Martinelli (julien.martinelli@aalto.fi)

You will consider the problem of identifying the dynamics of a biological network from time series measurements. This is a complex reverse engineering problem. Usually, when facing a biological question, modellers perform a time consuming literature review and design a model. The algorithms tackled here attempt to learn a dynamical model directly from data. The best competitors currently involve sparse regression methods and learn an ODE system using an arbitrary large library of predefined functions. The Bachelor's Thesis will include a literature review of the state of the art. Experiments in Python can also be carried out on some synthetic biological networks to further understand the algorithms and how they perform w.r.t. to standard features for biological data: initial conditions, noise, sparse sampling, irregular observation grid... Prerequisite: Ordinary differential equations ; Sparse regression methods (e.g. LASSO). Some Bayesian theory might be helpful. Experience with Python would help a lot for the coding part.

JL1: Comparative of security tools for the cloud

Tutor: Jose Luis Martin Navarro (jose.martinnavarro@aalto.fi)

Kubernetes is an open-source software for automating management of computerized services, such as docker images. Despite its benefits, there are concerns on the security of Kubernetes deployments. According to the latest survey from the Cloud Native Computing foundation, security is the second biggest challenge in using/deploying containers for respondents located in Europe. There are open source tools that address some of the security concerns of the community, but there is not a clear consensus on what does it take to secure a deployment. The focus of this seminar topic is to review the existing security tools for Kubernetes/docker.

JL2: Managing secrets in cloud applications

Tutor: Jose Luis Martin Navarro (jose.martinnavarro@aalto.fi)

With the adoption of distributed cloud infrastructure new solutions are needed to handle the security of these new environments. Since applications are described in declarative documents, it is a challenge to handle secrets such as passwords, keys or certificates without storing them in plain text. The purpose of this topic is to review the different approaches to secret management in docker and Kubernetes.

JB: Software supply chain security

Tutor: Jacopo Bufalino (jacopo.bufalino@aalto.fi)

Vulnerable code can leak into a production system in every step of the software supply chain. The SLSA standard has been created to address the key supply chain threats by verifying the source, build and dependency integrity. The goal of this topic is to investigate the various threats affecting the software supply chain, related (but not limited) to: - Source code integrity - Dependency integrity - Language specific dependency managers (pip, npm, RubyGems) -Container images used as dependencies - Artifact management - How to secure single-page apps, containers, Helm charts - CI/CD pipeline security Students are welcome to propose other topics in the same area. For example, it is possible to analyse the SLSA standard and propose changes to it. Alternatively, the student can suggest extensions to the SLSA standard to include, e.g., integrity checks during the deployment to a production environment. The paper can focus on an individual supply-chain threat or on the standard for a specific threat. Students must have prior knowledge of the relevant technologies (e.g., Linux containers, package managers, CI/CD platforms) The student must be able to conduct independent experiments to create examples for the paper. This topic can be chosen by multiple students, and it is possible for two students to co-author the seminar paper. The first tutoring rounds will be conducted as group meetings. When co-authoring, it is important that the students conduct the research and writing together to produce slightly more ambitious results.

JH: Machine learning for fog and edge service placement

Tutor: Jaakko Harjuhahto (jaakko.harjuhahto@aalto.fi)

The fog and edge computing paradigms propose placing services near users and devices, instead of centralizing them in warehouse scale data centers, i.e., the cloud. One of the key challenges is defining where and when services are placed. Instead of explicitly developing a placement algorithm, machine learning offers another alternative for solving this challenging multi-objective optimization problem. For this topic, perform a literature review on the use of machine learning methods for fog/edge service placement.

HM1: Animation of interactions with dynamic objects using neural networks

Tutor: Henry Mauranen (henry.mauranen@aalto.fi)

In recent years, there has been progress in animating movements such as walking and running using deep neural networks. Additionally, there have been some convincing approaches to animate static object interactions. This research topic will study approaches for animating locomotion interactions with dynamic objects using deep learning. The objective of this topic is to give you an overview of the current state of the art. For eager students, you will also have the opportunity to explore and implement some of the researched techniques and potentially create or continue your work into a publication in the domain.

HM2: Deep learning based dynamics for animation and biomechanics

Tutor: Henry Mauranen (henry.mauranen@aalto.fi)

Research in applying deep learning to find human poses and kinematics is quite well established. However, dynamics are not often discussed in this context. Dynamics are essential for biomechanical applications, and introduction of extra information could improve the deep learning based pose estimates and animations. In this research topic, we will be investigating the use of machine learning techniques to model the dynamics of the body for animation and biomechanics. The goal is to gain a deeper understanding of body mechanics and create more realistic animations. The objective of this topic is to give you an overview of the current state of the art. For eager students, you will also have the opportunity to explore and implement some of the researched techniques and potentially create or continue your work into a publication in the domain.

CB: Secure Multi-Party Computation

Tutor: Christopher Brzuska (chris.brzuska@aalto.fi)

This topic has CS-E4340 Cryptography or MS-1687 Advanced Topics in Cryptography (or equivalent) as pre-requisit. You will not be able to read research articles in cryptography without pre-requisits in cryptography, and gaining the pre-requisits during the course is impossible due to the tight schedule. Secure multi-party computation allows several parties P_1,...,P_n with secret input x_1,...,x_n to jointly compute a function f(x_1,..,x_n)=y such that everyone learns the output y, but nothing else about the inputs. In this way, for examples, hospitals can combine medical data in a privacy-preserving way. There have also been first discussions on combining MPC in order to achieve privacy-preserving distributed machine-learning. Secure multi-party computation (MPC) is a quite large field, and many topics are possible.

LG: Formal Verification of Security Properties

Tutor: Lachlan Gunn (lachlan.gunn@aalto.fi)

Formal methods have become a basic element of the cryptographer’s toolbox: we use formal methods to verify the algorithms, their implementations, and the hardware that they run on.   Firefox, for example, uses HACL* [1] in its cryptographic implementations, a mechanically-verified implementation of various cryptographic primitives.

Formal verification has been applied to many other systems:

  • Software implementing the Signal messaging protocol [2]
  • The software running the Ariane 5 rocket, and various metro lines [3]
  • The TLS 1.3 [4] and WireGuard [5] protocols

In this project, you will examine aspects of how to find bugs and demonstrate security using formal verification.  Each of up to six students will examine a different aspect of the topic; some examples:

  • How to join different proofs together to prove the security of a large system
  • How different programming languages are better or worse suited to formal verification
  • How different proof techniques can aid the user by automation

JR2: Towards Autonomous Multi-UAV Wireless Networks: A Survey of Reinforcement Learning-based Approaches  (Customized topic, do not select)

Tutor: Jäntti Riku (riku.jantti@aalto.fi)

Student: Bai Yu

Unmanned aerial vehicles (UAVs), an emerging flexible flying platform, have been applied in various fields in recent years because of their high flexibility and low deployment costs. The multi-UAV wireless network (MUWN) is promising in sophisticated situations, as it has enhanced coverage and service resources, and allows the simultaneous coordination and cooperation of multiple UAVs to accomplish large-scale (multi-objective) tasks. Reinforcement learning (RL) is considered to be one of the most promising ways to achieve artificial intelligence, which can help to construct autonomous and intelligent UAV networks.
