Researchers have developed a novel method for conditioning protein generation using a training-free stochastic-attention sampler. By incorporating a multiplicity ratio into the sampler's logits, the generation process can be shifted from a broad protein family towards a specific subset of interest. This technique was tested across five Pfam families, demonstrating that attention mechanisms accurately followed the analytic target, though the recovery of specific residue markers depended on the separation of designated and background sequences via principal component analysis. A weighted profile HMM showed more direct recovery of these markers, while stochastic attention achieved lower perplexity in a comparison involving Kunitz sequences. AI
