Reasoning about MDPs Abstractly: Bayesian Policy Search with Uncertain Prior Knowledge

Many real-world problems fall in the category of sequential decision-making under uncertainty; Markov Decision Processes (MDPs) are a common method for modeling such problems. To solve an MDP, one could start from scratch or one could already have an idea of what good policies look like. Furthermore, there could be uncertainty in this idea. In...

CCS Reservoir Simulation using Graph Neural Networks: Building ML solutions for efficient CO2 subsurface modelling

Reducing cost and improving computability of reservoir simulation is an important goal in the process of enabling CCS (Carbon Capture \& Storage) as a large-scale technology for mitigating CO2 emissions. In terms of computation time data-driven approaches have potential to outweigh the performance of numerical reservoir simulators, learning...

Positive Eating: Fostering Wellbeing in Healthy Eating Experiences Supported by AI-Driven Systems

Is healthy eating simply the intake of correct quantities of certain nutrients, regardless of how and where? This project addresses improving wellbeing within the broad context of eating. <br/><br/>Eating-related guidance products have a hyper-focus on nutrition and/or weight loss, to the detriment of a wider definition of “health”. Wellbeing is...

A System for Model Diagnosis centered around Human Computation

Machine learning (ML) systems for computer vision applications are widely deployed in decision-making contexts, including high-stakes domains such as autonomous driving and medical diagnosis. While largely accelerating the decision-making process, those systems have been found to suffer from a severe issue of reliability, i.e., they can easily...

Creating Monsters: crafting gender ambiguous child toys through reflexive designer-AI interactions

Growing up, social constructs like roles, norms and values are being internalised and naturalised. Despite offering a sense of stability, such constructs also prohibit equality, justice and diversity, by pushing people into categories, roles and norms they do not represent. However, once internalised, social constructs fall under the surface of...
