grounded_scan

  • Description:

Grounded SCAN (gSCAN) is a synthetic dataset for evaluating compositional generalization in situated language understanding. gSCAN pairs natural language instructions with action sequences, and requires the agent to interpret instructions within the context of a grid-based visual navigation environment.
