New Factor-Graph Approach Optimizes Protein MSA Subsampling

Researchers have developed AP-REASONER, a novel factor-graph approach for subsampling Multiple Sequence Alignments (MSAs) in protein language models. This method treats MSA subsampling as an optimization problem, allowing for control over evolutionary signals like query identity and diversity. Experiments demonstrate that AP-REASONER outperforms traditional subsampling heuristics on structure-sensitive downstream tasks, enabling the controllable recovery of alternative protein conformations.
