HALO: Human-AI collaborative system for drug discovery molecular hypothesis generation
_xiang_chen_ · x · 2026-08-12
Researchers introduced HALO, a human-AI collaborative system designed to accelerate molecular hypothesis generation in drug discovery by assisting scientists' abductive reasoning. Rather than fully automating the research process, the system takes a symbiotic approach, embedding AI into scientists' reasoning to support the discovery of novel molecular edits.
- Core Mechanism: Proposes a "co-abduction" framework to help experts with candidate clustering, strategy identification, and multi-strategy synthesis.
- Expert Study: In a study involving 10 medicinal chemists, HALO significantly facilitated abductive reasoning and enabled participants to produce higher-quality, more diverse candidate molecules.
- Background: Developed by a UCLA team, the paper has been accepted to UIST 2026.
