New MODS framework enables multi-objective protein optimization via diffusion models

Researchers have developed MODS, a modular framework for multi-objective protein optimization using diffusion models. This approach allows for simultaneous improvement of multiple protein properties by steering the generation process with varying scalar rewards. MODS can be integrated with different diffusion models and steering procedures, and it updates predictive surrogates without retraining the generative model after each evaluation batch. Experiments on six protein optimization tasks demonstrated that MODS achieves competitive final hypervolume and outperforms baseline methods on several tasks, offering an effective strategy for protein design with limited feedback.
