• AgentPLM: Agentic Protein Language Models with Reasoning-Augmented Decoding for Protein Sequence Design

  Sahil Rahman, Maxx Richard Rahman · 2 de junio de 2026

We introduce AgentPLM, which addresses this by equ…

• Counterfactual Peptide Editing for Causal TCR--pMHC Binding Inference

  Sanjar Khudoyberdiev, Arman Bekov · 16 de abril de 2026

  Neural models for TCR-pMHC binding prediction are susceptible to shortcut learning: they exploit spurious correlations in training data -- such as peptide length bias or V-gene co-occurrence -- rather than the physical binding interface. This renders predictions brittle under family-held-out and dis…
