Perspectives on Bayesian Optimization for HCI
In this position paper we discuss optimization in the HCI
domain based on our experiences with Bayesian methods
for modeling and optimization of audio systems, including
challenges related to evaluating, designing, and optimizing
such interfaces. We outline and demonstrate how a
combined Bayesian modeling and optimization approach
provides a flexible framework for integrating various user
and content attributes, while also supporting model-based
optimization of HCI systems. Finally, we discuss current
and future research direction and applications, such as
inferring user needs and optimizing interfaces for
computer assisted teaching
Bayesian multitask inverse reinforcement learning
We generalise the problem of inverse reinforcement learning to multiple
tasks, from multiple demonstrations. Each one may represent one expert trying
to solve a different task, or as different experts trying to solve the same
task. Our main contribution is to formalise the problem as statistical
preference elicitation, via a number of structured priors, whose form captures
our biases about the relatedness of different tasks or expert policies. In
doing so, we introduce a prior on policy optimality, which is more natural to
specify. We show that our framework allows us not only to learn to efficiently
from multiple experts but to also effectively differentiate between the goals
of each. Possible applications include analysing the intrinsic motivations of
subjects in behavioural experiments and learning from multiple teachers.Comment: Corrected version. 13 pages, 8 figure
