Sequential decision-making problems are problems where the goal is to find a sequence of actions that complete a task in an environment. A particularly difficult type of sequential decision-making problem to solve is one in which the environment has sparse rewards, a large state space, and where the goal is to complete a complex task. In this...

Several algorithms can often be used to solve a complex problem, such as the SAT problem or the graph coloring problem. Those algorithms differ in terms of speed based on the size or other features of the problem. Some algorithms perform much faster on a small size while others perform noticeably better on a larger instance. The optimization...

Decision tree learning is widely done heuristically, but advances in the field of optimal decision trees have made them a more prominent subject of research. However, current methods for optimal decision trees tend to overlook the metric of robustness. Our research wants to find out whether the robustness of optimal decision trees can be...

Machine learning can be used to classify patients in a hospital. Here, the classifier has to minimize the cost of misclassifying the patient and minimize the costs of the tests. Unfortunately, obtaining features may be costly, e.g., taking blood tests or doing an x-ray scan. Furthermore, it is possible that acquiring those test results may take...

Various pathologies can occur when independent learners are used in cooperative Multi-Agent Reinforcement Learning. One such pathology is Relative Overgeneralisation, which manifests when a suboptimal Nash Equilibrium in the joint action space of a problem is preferred over an optimal Equilibrium. Approaches exist to combat relative...

Most cooperative games are tackled by creating a team of agents who are optimised for each other and the problem. Creating an agent who can play in a variety of teams without any foreknowledge of its partner is a different challenge. These AI systems could useful for human-AI interaction as different people bring a lot of variance into the...

Multi-agent multi-target catching is the act of multiple agents trying to catch multiple moving targets. The exact algorithms created for such chases are generally targets that are actively trying to get as far as possible, while the agents try to prevent that. However, these algorithms can get much more efficient whenever targets also want to...

A structured CNN filter basis allows incorporating priors about natural image statistics and thus require less training examples to learn, saving valuable annotation time. Here, we build on the Gaussian derivative CNN filter basis that learn both the orientation and scale of the filters. However, this Gaussian filter basis definition depends on...

Information-Centric Networking (ICN) is a new approach for a more scalable and effective internet. ICN has many benefits, namely: ubiquitous caching, location-independent content routing and content-centric security. Despite the aforementioned benefits, the network paradigm is not ready to replace the current host-centric network as ICN is...

Large volumes of medical data (MD) are continuously generated by the healthcare domain. When sharing these data, issues arise regarding privacy and security. To solve these issues, a permissioned blockchain (BC) can be used, but since blockchains do not have access control (AC) as a default feature, the integration of an access control system ...

The continuous generation of a large volume of health data from different sources has led to healthcare being a data-intensive domain. To achieve innovative advances in medical treatment procedures and to provide personalized healthcare services to the patients this data needs to be shared among different medical facilities. However, because...

Information-Centric Networking (ICN) is a networking paradigm proposed to replace the current IP network. It uses in-network caching to enhance availability. However, as a clean slate approach is unlikely to work, an architecture that allows for the two paradigms to coexist needs to me used to facilitate the transition. Several such...

Information-centric Networking (ICN) is the revolution of the internet due to its many benefit over the current internet infrastructure, namely caching, location-independent routing, and data-centric security. ICN ensures seamless data transfer due to its content-centric nature. Due to its content-centric nature, it is a must to ensure that...

Information-Centric Networking (ICN) is a common approach to the Internet of the future. However, transitioning to the new Internet architecture right away is impractical if not impossible. Hence, there will be some period of coexistence of ICN and IP. This paper investigates the support of security and privacy features in the three most popular...

Patient monitoring and clinical trial management generate continuous large volumes of healthcare data, causing the healthcare industry to be a data-intensive domain. Existing data storage techniques and access mechanics in the healthcare domain exhibit several challenges related to data security, patient privacy, and interoperability. Blockchain...

The health industry is a data-intensive domain. Sharing medical data between medical facilities is necessary for providing good healthcare as well as for research in the healthcare domain. However, due to the sensitive and personal nature of health data, challenges arise when sharing this data. Consent management is a key aspect. The use of...

In the past few years, there has been much research in the field of Autonomous Vehicles (AV). If AVs are implemented in our daily lives, this could have many advantages. Before this can happen, safe driver models need to be designed which control the AVs. One technique that is suitable to create these models is Reinforcement Learning (RL). A...

We consider a simplified version of the Monte Carlo tree search (MCTS) problem, a problem where, given a game tree with stochastic reward, one is tasked with finding the best move from the root. This problem is well studied, and recently impressive results have been obtained. For example, in 2016, when the AlphaGo program beat the professional...

Side-channel attacks (SCA), which use unintended leakage to retrieve a secret cryptographic key, have become more sophisticated over time. With the recent successes of machine learning (ML) and especially deep learning (DL) techniques against cryptographic implementations even in the presence of dedicated countermeasures, various methods have...

According to the United Nations, the amount of money laundered worldwide each year is an estimated 2 - 5% of global GDP (equivalent to $800 billion to $2 trillion in US dollars). This is money that criminal enterprises rely on to oper- ate. For that reason, the European Union demands that gatekeepers (banks and other obliged entities) apply...
