PEACCEL at NeurIPS 2025: Epistasis-Aware AI for Drug Discovery
23 December 2025

NeurIPS, San Diego, December 2025. PEACCEL presented new research on hypercube- constrained graph learning for protein fitness prediction, emphasizing constraint handling and epistasis modeling, two levers with direct impact on discovery timelines and hit quality.

What we showcased
- Hypercube-Constrained Graph Learning to enforce smoothness only where biology supports it (i.e., constraint-aware learning over mutational neighborhoods).
- Wavelet-denoised supervision to counter measurement noise and sparsity in sequence–fitness labels, boosting label-efficiency for low-N regimes common in early discovery.
- Epistasis-aware prediction on discrete mutational spaces (Hamming hypercubes), improving generalization to unseen variants while respecting feasibility constraints relevant to downstream design.
Why it matters for drug discovery and design
- Higher hit rates with fewer assays. Constraint-aware training and denoising reduce experimental burden while preserving accuracy on rugged, epistatic landscapes.
- Faster iteration cycles. Semi-supervised learning leverages unlabeled variants accelerating prioritization before scale-up.
- Better transfer to developability filters. Graph-structured outputs and calibrated constraints integrate cleanly with ADMET and safety heuristics.
Collaboration footprint
This work was delivered with academic partners across Australia and the United States, reflecting a globally distributed R&D model aligned with pharma expectations for translational validation.
