New preference-based learning framework enhances antibody design

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel preference-based learning framework to improve antibody expression ranking, a crucial step in antibody design. This method leverages scarce quantitative expression data alongside a large dataset of weak positive supervision from immunization data. By adapting Direct Preference Optimization (DPO) for protein language models and incorporating IMGT-based alignment, the framework efficiently trains on variable-length sequences. Evaluations on a substantial internal dataset demonstrated that this approach consistently surpasses existing baselines, offering a scalable solution for optimizing antibody expressibility in data-limited scenarios.

    Preference-based Antibody Expression Ranking: Scaling with Large-scale Weak Supervision

    arXiv:2607.16263v1 Announce Type: new Abstract: Antibody expression ranking is a critical task in antibody design, yet its modelling is severely hindered by the scarcity of labeled experimental data. To address this, we propose a unified preference-based learning framework that i…
