AttnCompress: Dynamic Attention-Guided Trajectory Compression for Software Engineering Agents

AttnCompress bridges the gap between semantic integrity and dynamic adaptability through three key mechanisms: structure-aware segmentation via perplexity (PPL) spikes to preserve the syntactic structure of code and logs, and relevance estimation using proxy attention weights to quantify the precise relevance of histor...

REER-PT: Reverse-Engineered Reasoning for Perplexity-Guided Pre-training Data Augmentation

Together, the perplexity analysis indicates improved continuation predictability, while the controlled pre-training experiments suggest that this augmentation can improve model performance without changing the standard pre-training objective.
