Query: VRKitchen: an Interactive 3D Virtual Environment for Task-oriented
  Learning   One of the main challenges of advancing task-oriented learning such as visual
task planning and reinforcement learning is the lack of realistic and
standardized environments for training and testing AI agents. Previously,
researchers often relied on ad-hoc lab environments. There have been recent
advances in virtual systems built with 3D physics engines and photo-realistic
rendering for indoor and outdoor environments, but the embodied agents in those
systems can only conduct simple interactions with the world (e.g., walking
around, moving objects, etc.). Most of the existing systems also do not allow
human participation in their simulated environments. In this work, we design
and implement a virtual reality (VR) system, VRKitchen, with integrated
functions which i) enable embodied agents powered by modern AI methods (e.g.,
planning, reinforcement learning, etc.) to perform complex tasks involving a
wide range of fine-grained object manipulations in a realistic environment, and
ii) allow human teachers to perform demonstrations to train agents (i.e.,
learning from demonstration). We also provide standardized evaluation
benchmarks and data collection tools to facilitate a broad use in research on
task-oriented learning and beyond.
