Trajectory Abstraction for the Science of Language Agent Behavior

Scientific studies of language agents need behavioral variables that support hypotheses across tasks and models.

Key points

  • We formulate this research problem as learning and testing a hierarchy of trajectory abstractions.
  • A concrete recursive procedure first measures role- and phase-indexed events, proposes temporally constrained relations, and tests their stability across conditions.
  • We derive a finite-depth bound for accepted reductions, identify protocol effects on fixed abstractions, and characterize realization disagreement and composition of abstraction error.
  • The formulation distinguishes this experimental approach from semantic taxonomies, qualitative theory induction, and behavior-model recovery.
