CG-Probes: Recovering Guardrail Directions from Patient Query Embeddings

Read the original on arXiv Computation and Language →

CG-Probes are a method for extracting guardrail directions—Medical Urgency, Psychological Urgency, and Topic Sensitivity—from patient query embeddings. By treating each risk axis as a linear direction in the normalized embedding space, the approach uses difference‑in‑means probing and contrastive pairs generated from clustered Czech oncology search queries. Evaluated on 200 queries graded by oncologists, the probes perform comparably to open‑weight and frontier LLMs while offering lower latency and requiring only search logs, axis definitions, and black‑box embedding access.

A general-purpose System One decision model for clinical records

The paper introduces Clinical System One (CS1), a 4‑billion‑parameter decision model that rapidly produces typed judgments from clinical records. Trained on 12.4 million Q&A pairs from 3.6 million patients, CS1 can answer multiple questions in a single forward pass, providing probability estimates for uncertain cases. In evaluations on 963,408 held‑out patients and 21 external datasets, CS1 outperformed larger open models and, when paired with a language‑model agent, efficiently identified trial‑eligible patients with far fewer tokens.

Retrieval-Augmented Interpretable Learning: Towards Task-Specific Zero-Shot Models in Healthcare

arXiv:2607. 17508v1 Announce Type: cross Abstract: We introduce Retrieval-Augmented Interpretable Learning (RAIL), a probabilistic meta-learning framework for zero-shot generation of task-specific interpretable models that synthesizes coefficient-space structure from natural-language task descriptions and a memory of previously learned task-specific predictors.

BiomedXPro: Prompt Optimization for Explainable Diagnosis with Biomedical Vision Language Models

BiomedXPro is an evolutionary framework that uses a large language model to automatically generate a diverse set of interpretable, natural‑language prompt pairs for disease diagnosis with biomedical vision‑language models. It addresses the lack of transparency in existing prompt optimization methods by producing prompts that are both understandable and aligned with clinically significant features. Experiments on multiple biomedical benchmarks show that BiomedXPro outperforms state‑of‑the‑art prompt‑tuning techniques, especially in few‑shot, data‑scarce scenarios.
