Briefings

Mirror is a self-supervised video-to-action model that learns task execution by attempting to follow visual plans in environments, then training on resulting video-action pairs. It outperforms leading learning-from-observation methods on Atari, OGBench, and DeepMind Control, achieving near-expert performance with oracle plans. On Minecraft BASALT, it outperforms methods with expert actions or hand-engineered knowledge, marking the first method to acquire an iron pickaxe through self-improvement alone without rewards or expert labels. In offline settings with expert labels but no environment interaction, it sets a new state of the art for obtaining diamonds.

Key points

• Mirror learns video-to-action mappings through environment interactions without prior action data or hand-crafted rewards.
• On Minecraft BASALT, it outperforms methods with access to expert actions or hand-engineered task knowledge.

Context

Video generative models serve as scalable visual planners for embodied agents, but executing plans requires video-to-action models trained on large human-collected datasets. This study introduces Mirror, a self-supervised approach that learns mappings via environment interactions, enabling agents to acquire capabilities without hand-crafted rewards or expert action data.

Limitations

Results are from a single preprint (arXiv:2610.24177v1) with no experimental replication or independent verification. Performance claims on Atari, OGBench, and DeepMind Control are based on single model runs without statistical significance testing. Minecraft results are limited to one specific environment (BASALT) and do not generalize to other Minecraft scenarios. No data on training duration, sample size, or hyperparameter tuning is provided.
