Researchers developed CDD (Contamination Detection via output Distribution) to identify data contamination in small language models by measuring output peakedness. The study found that CDD only works when fine-tuning produces verbatim memorization, failing at chance level with parameter-efficient methods like low-rank adaptation that avoid memorization.
Research paper compares three sinusoidal models for speech and audio signal processing: standard Sinusoidal Model (SM), Exponentially Damped Sinusoidal Model (EDSM), and extended adaptive Quasi-Harmonic Model (eaQHM).
