Implicit Neural Representations of Individual Behavior
Researchers have developed a new self-supervised generative model called Behavioral INR, which adapts implicit neural representations (INRs) to learn policy representations from unlabeled behavioral data. This model treats each data point as samples from an underlying function, allowing it to handle variable episode lengths and different sampling granularities. Behavioral INR aims to infer policy identity without supervision and defines new metrics for out-of-distribution shifts in policies. AI
