arXiv:2605.27919v1 Announce Type: cross Abstract: Learning visuomotor policies via behavior cloning typically involves mimicking expert demonstrations collected by human operators. However, natural human demonstrations inherently contain high-frequency noise, such as intermittent jerks, pauses, and action jitter. Training policies to directly imitate these raw trajectories inevitably causes the model to inherit these suboptimal behaviors. This pathology is particularly pronounced in diffusion-based policies, where iterative denoising steps can inadvertently amplify high-frequency artifacts at
The proliferation of diffusion models in AI research is leading to a focus on refining their application to complex tasks like visuomotor policy learning, necessitating solutions to inherent noise amplification issues.
This research addresses a critical limitation in training robust AI agents for physical tasks, which is crucial for advancing robotics and autonomous systems beyond human-mimicry imperfections.
The ability to filter high-frequency noise from human demonstrations will improve the reliability and efficiency of AI policies trained via behavior cloning, particularly for diffusion-based methods.
