Med-PaLM 2 builds on top of PaLM 2, the latest SOTA LLM from @GoogleAI We further finetune / align the model to the requirements of the medical domain and introduce ensemble refinement as a simple new prompting strategy to improve the model’s medical reasoning capabilities.

Super excited about this work! Underspecification has important implications when building AI models for healthcare and this paper has several examples from medical imaging, EHR, genomics and even epidemiology to illustrate this. Please give it a read!

We also introduce a new adversarial questions benchmark dataset designed to elicit model answers with potential for harm and bias and probe the safety and limitations of LLMs in the medical domain.

Excellent overview from Nathan/Ian. If you work in AI or even just have a passing interest, well worth your time. Glad to see both my current team's ( @GoogleHealth ) research breakthroughs in AI for ophthalmology and mammography and work with previous team on VQA (LORRA) featured

@taotu831 @AziziShekoofeh @HardyShakerman @peteflorence @DannyDriess @thekaransinghal @alan_karthi @GoogleAI Finally, to understand the clinical applicability of Med-PaLM M, we conducted a radiologist evaluation of AI generated reports across model scales. Clinically significant error rate for Med-PaLM M on par with radiologists from prior studies suggesting potential clinical utility.

Paper has many insights but one that was super interesting was the significant average predictive disagreement & complementarity we observed in representations trained using supervised & self supervised pre-training. Could be an exciting direction of research for the community!

@le_roux_nicolas This depends on the research topic no? Lightweight reviews are common if you do general research on open data but if work touches nuanced areas, the process is strict. Context: I work in health and end up spending considerable time shepherding papers through internal reviews.

This has been a riveting read thus far from @charlesgraeber . Immunotherapy has a number of interesting parallels to AI going through cycles of hype and bust and rebirth and the single minded dedication of researchers to keep going despite all odds.

Med-PaLM 2 approaches or exceeds SOTA on multiple medical question answering benchmarks. In particular, it reaches a score of 86.5% on MEDQA (USMLE) dataset matching performance of expert test takers (>18% over Med-PaLM). It also reaches a new SOTA of 81.8% on PubMedQA.

While further studies are necessary to validate the efficacy of these LLMs in real-world clinical settings, these results nevertheless highlight the rapid progress we are making towards expert-level performance in medical question answering. The possibilities are exciting!
