New Taxonomy Reveals Where Retrieval-Based Medical Fact Verification Fails

Retrieval-augmented generation is standard for verifying LLM claims in clinical settings, yet aggregate metrics like F1 hide specific failure modes. This paper introduces two comprehensive taxonomies to diagnose errors, moving beyond opaque scoring. Grounded in case studies on MedExpert and other datasets, the framework decomposes failures into retrieval-stage errors across five quality dimensions.

  • Aggregate F1 scores obscure the root causes of hallucinations in medical RAG systems.
  • New taxonomies decompose retrieval failures into five distinct quality dimensions.
  • Diagnostics work without gold answers or annotated evidence, enabling scalable auditing.
  • Framework enables precise debugging of retrieval-stage errors in high-stakes clinical AI.

Adaptive Recs: Inference, Evals, and System Design Constraints

Mallika Rao argues that the real challenge in adaptive recommendation systems is not model architecture but production engineering. She highlights the necessity of managing real-time feedback loops, retrieval freshness, and multi-stage orchestration. The approach focuses on meeting strict latency, cost, and observability budgets while enabling continuous learning.

  • Complexity lives in ops, not just model weights
  • Real-time feedback loops drive system evolution
  • Retrieval freshness is critical for accuracy
  • Latency and cost budgets dictate architecture
  • Multi-stage orchestration enables continuous learning
