Protein language models achieve optimal fitness prediction performance at moderate sequence likelihood levels, with larger models often overestimating likelihoods and reducing accuracy.
- Why it matters: Understanding how model size and training data influence fitness prediction is crucial for improving protein engineering and avoiding misleading results from overly large models.
- What they did: The study analyzed how model size, training data, and stochastic factors bias predicted sequence likelihoods, comparing these to evolutionary patterns in homologs across various proteins.
- The result: Findings reveal that moderate p(sequence) levels best reflect true fitness landscapes, guiding future model development and application to enhance accuracy in protein design.
