Deep learning-based antimicrobial peptide (AMP) discovery faces critical
challenges such as low experimental hit rates as well as the need for nuanced
controllability and efficient modeling of peptide properties. To address these
challenges, we introduce OmegAMP, a framework that leverages a diffusion-based
generative model with efficient low-dimensional embeddings, precise
controllability mechanisms, and novel classifiers with drastically reduced
false positive rates for candidate filtering. OmegAMP enables the targeted
generation of AMPs with specific physicochemical properties, activity profiles,
and species-specific effectiveness. Moreover, it maximizes sample diversity
while ensuring faithfulness to the underlying data distribution during
generation. We demonstrate that OmegAMP achieves state-of-the-art performance
across all stages of the AMP discovery pipeline, significantly advancing the
potential of computational frameworks in combating antimicrobial resistance.
