Multi Step Task Trajectory Indexing And Retrieval

via “task-category-hierarchical-filtering”

Dataset by nvidia. 3,34,635 downloads.

Unique: Implements tree-indexed task hierarchy for 334K GR00T-X trajectories enabling O(log N) hierarchical filtering and task similarity search, critical for curriculum learning and modular skill training at scale

vs others: Faster than flat task filtering because hierarchical index enables pruning of irrelevant subtrees, and more structured than keyword-based filtering because task relationships are explicitly modeled
