Calibrating Post-Training Feature Shifts for LLM Data Contamination Detection

CalibDCD is proposed, a broadly applicable calibration framework for feature-based DCD methods, comprising Multi-View Shift Detection, which identifies recurring feature shifts associated with post-training, and Bounded Feature Correction, which selectively mitigates their influence on membership prediction.

EvoSQL: Memory-Augmented Critic-Generator Co-Evolution for Text-to-SQL

EvoSQL is presented, a co-evolution framework that formulates SQL synthesis as an iterative interaction between a generator and a critic and maintains a contextualized candidate memory, verifies SQL candidates with both execution signals and LLM-based critique, and updates its memory through utility-guided aggregation.
