Generative Co-Design of Antibody Sequences and Structures via Black-Box Guidance in a Shared Latent Space

IJCAI 2025

Advancements in deep generative models have enabled the joint modeling of antibody sequence and structure, given the antigen-antibody complex as context. However, existing approaches for optimizing complementarity-determining regions (CDRs) to improve developability properties operate in the raw dat

Boosting the Transferability of Adversarial Samples via Attention

CVPR 2020poster

The widespread deployment of deep models necessitates the assessment of model vulnerability in practice, especially for safety- and security-sensitive domains such as autonomous driving and medical diagnosis. Transfer-based attacks against image classifiers thus elicit mounting interest, where attac…
