CaReCoS - ZCH: leaderboard
CaReCoS (Centific, 2026) questions on ZCH neonatal and paediatric heart-sound recordings with structural diagnoses such as septal defects, answered from a mel-spectrogram image. An LLM judge scores each answer against the reference; the score is accuracy in percent, higher is better.
Metric: Accuracy (%) of one-to-two-sentence answers to clinically grounded questions about a mel-spectrogram image of the recording, judged by an LLM against the reference (strict factual matching for explicit questions, relaxed semantic matching for inferred ones); the 80 ZCH neonatal and paediatric heart-sound questions; higher is better. Source: arxiv.org. Saturation forecast: Around July 2027. 9 models tracked.
