New PETA framework efficiently adapts AI models for drug discovery

Researchers have developed PETA, a parameter-efficient framework for adapting pretrained virtual screening models to specific protein pockets. This method addresses the computational cost of retraining entire models by directly adapting them at test time. PETA constructs pocket-specific negative examples and uses an embedding-space mixup technique to create more challenging ranking tasks, emphasizing the suppression of invalid candidates. Experiments show that PETA, by updating only LayerNorm parameters, outperforms both pretrained and fully retrained models on diverse benchmarks. AI

IMPACT This method could significantly reduce the computational cost of customizing AI models for specific drug discovery tasks.
