What values should an agent align with?
An empirical comparison of general and context-specific values
The pursuit of values drives human behavior and promotes cooperation. Existing research is focused on general values (e.g., Schwartz) that transcend contexts. However, context-specific values are necessary to (1) understand human decisions, and (2) engineer intelligent agents tha

Confronting Narratives of Driving Automation through Contestational Artifacts
In this paper, we problematize popular narratives of driving automation. Whether positive or negative, these propagate simplistic assumptions about human abilities and reinforce technocratic approaches to mobility innovation. We build on narrative approaches to participatory rese

Aggregation of energy consumption forecasts across spatial levels
Using CNN-LSTM forecasts of lower spatial levels to forecast on higher spatial levels
Bottom up load forecasting, is a technique where energy consumption forecasts are made on lower spatial levels, after which the resulting forecasts are aggregated to form forecasts of higher spatial levels. With the current move to renewable energy sources and the importance of r

Inverse Reinforcement Learning (IRL) in Presence of Risk and Uncertainty Related Cognitive Biases
To what extent can IRL learn rewards from expert demonstrations with loss and risk aversion?
A key issue in Reinforcement Learning (RL) research is the difficulty of defining rewards. Inverse Reinforcement Learning (IRL) is a technique that addresses this challenge by learning the rewards from expert demonstrations. In a realistic setting, expert demonstrations are colle

Reinforcement learning with domain-specific relational inductive biases
Using Graph Neural Networks and domain knowledge
Reinforcement Learning (RL) has been used to successfully train agents for many tasks, but generalizing to a different task - or even unseen examples of the same task - remains difficult. In this thesis, Deep Reinforcement Learning (DRL) is combined with Graph Neural Networks (GN

Investigating Inverse Reinforcement Learning from Human Behavior
Effect of Demonstrations with Temporal Biases on Learning Rewards using Inverse Reinforcement Learning
Inverse Reinforcement Learning (IRL) is a machine learning technique used for learning rewards from the behavior of an expert agent. With complex agents, such as humans, the maximized reward may not be easily retrievable. This is because humans are prone to cognitive biases. Cogn

Mechanism to detect mismatches and provide recommendations about the users' preference in negotiation support systems
A case study about issue weight mismatches with the pocket negotiator
Negotiation Support Systems (NSSs) can provide help based on the preference setting (domain, issue weights, issue ranking, strategies, etc.) of the users of the systems. However, sometimes the users of the systems might make mistakes in the preference setting. With wrong preferen
