Active Third-Person Imitation Learning
Timo Klein, Susanna Weinberger, Adish Singla +1
We consider the problem of third-person imitation learning with the additional challenge that the learner must select the perspective from which they observe the expert. In our set…
Posterior Consistency for Missing Data in Variational Autoencoders
Timur Sudak, Sebastian Tschiatschek
We consider the problem of learning Variational Autoencoders (VAEs), i.e., a type of deep generative model, from data with missing values. Such data is omnipresent in real-world ap…
Learning Safety Constraints from Demonstrations with Unknown Rewards
David Lindner, Xin Chen, Sebastian Tschiatschek +2
We propose Convex Constraint Learning for Reinforcement Learning (CoCoRL), a novel approach for inferring shared constraints in a Constrained Markov Decision Process (CMDP) from a…
Interactively Learning Preference Constraints in Linear Bandits
David Lindner, Sebastian Tschiatschek, Katja Hofmann +1
We study sequential decision-making with known rewards and unknown constraints, motivated by situations where the constraints represent expensive-to-evaluate human preferences, suc…
Equity and Fairness of Bayesian Knowledge Tracing
Sebastian Tschiatschek, Maria Knobelsdorf, Adish Singla
We consider the equity and fairness of curricula derived from Knowledge Tracing models. We begin by defining a unifying notion of an equitable tutoring system as a system that achi…
Option Transfer and SMDP Abstraction with Successor Features
Dongge Han, Sebastian Tschiatschek
Abstraction plays an important role in the generalisation of knowledge and skills and is key to sample efficient learning. In this work, we study joint temporal and state abstracti…
