BATMAN is an interpretable Bayesian model for predicting the antigens that activate a T cell receptor (TCR). BATMAN predicts TCR activation by mutant peptides based on their distances to the TCR's index peptide. The peptide-to-index distance is a product of a learned positional weight profile vector, corresponding to effects of mutated residues at different positions in the sequence, and a learned amino acid substitution distance from the index peptide amino acid to the mutant amino acid.

BATMAN can be trained in two modes: (1) within-TCR, where the train and test peptides are associated with the same TCR, and BATMAN-inferred positional weight profiles are TCR-specific, and (2) leave-one-TCR-out, where peptides are tested for activation of a TCR left out of the training data, and BATMAN-inferred positional weight profile is common across all TCRs.

BATMAN outperforms existing TCR-antigen methods, reveals structural and biochemical predictors of TCR-antigen interactions, and can predict polyclonal T cell responses and TCR targets with high sequence dissimilarity.
