2nd Workshop on Human-Interactive Robot Learning
(HIRL)

at HRI'23

Main HRI Conference Website

With robots poised to enter our daily environments, they will not only need to work for people, but also learn from them. An active area of investigation in the robotics, machine learning, and human-robot interaction communities is the design of teachable robotic agents that can learn interactively from human input. To refer to these research efforts, we use the umbrella term Human-Interactive Robot Learning (HIRL). While algorithmic solutions for robots learning from people have been investigated in a variety of ways, HIRL, as a fairly new research area, is still lacking:
1) a formal set of definitions to classify related but distinct research problems or solutions.
2) benchmark tasks, interactions, and metrics to evaluate the performance of HIRL algorithms and interactions.
3) clear long-term research challenges to be addressed by different communities.

Last year we began consolidating the needed definitions and vocabulary to enable fruitful discussions between researchers from these interdiciplinary fields, and identified a preliminary list of long, medium, and short-term research problems for the community to tackle, and existing tools and frameworks that can be leveraged to this end. This workshop will build upon these discussions, focusing on promoting the specification and design of HIRL benchmarks.

The topics of interest for this workshop include, but are not limited to:

Learning from demonstration (LfD), learning by imitation, or learning from observation
Inverse reinforcement learning
Interactive reinforcement learning (IntRL)
Robot learning from human feedback (including advice, corrections, etc.)
Standardized task development for HIRL
Evaluation metrics for learners and teachers
Social signal processing for human teaching behaviors
Natural teaching interfaces
Teacher-learner adaptation
Human-guided exploration
Human-in-the-loop lifelong learning
