VOI LabRanker

Concise, single-script pipeline to rank ICU lab tests by value-of-information.

Script

• lab_test_ranker.py: downloads PhysioNet/CinC 2012 set-A, preprocesses 48h sequences, trains a dual-head Transformer (mortality + mech-vent within 6h), and produces paper-ready artifacts.

Run

python3 lab_test_ranker.py

No flags required; configuration is in-script.

Outputs

• lab_rank_results/ with summary.txt, tables/metrics.json, figs/, and best_model.pt.

Features

• Counterfactual masking utilities (cross-entropy gain per lab).
• Validation-only global scoring to avoid leakage.
• Budget and optional cost-aware evaluation.
• Redundancy audit and lead-time stats.
