Researchers have developed Q-BioLat, a new framework for optimizing protein fitness landscapes. This method maps protein language model embeddings to compact binary codes, enabling the use of quadratic unconstrained binary optimization (QUBO) for search. The framework emphasizes the impact of binary encodings on the optimization process, showing that different encodings can lead to varied search trajectories and local optima, even with similar predictive accuracy. Experiments using Green fluorescent protein (GFP) and AAV fitness data from ProteinGym demonstrate that Q-BioLat, particularly when combined with principal component analysis (PCA) and median thresholding, outperforms variational auto-encoder (VAE) baselines in creating decodable binary spaces for optimization.
