A new research paper published on arXiv explores the challenges of behavioral cloning when a single observation can lead to multiple valid actions. The study, titled "Understanding Multimodal Failure in Action-Chunking Behavioral Cloning," details how different parameterizations of multimodal policies exhibit distinct failure modes. It proposes regularization techniques for latent-variable policies to improve sampling reliability and discusses constraints on action-space generative policies related to the smoothness of action transport.
