CFP-Gen: Combinatorial Functional Protein Generation via Diffusion Language Models

ICML 2025poster

Existing PLMs generate protein sequences based on a single-condition constraint from a specific modality, struggling to simultaneously satisfy multiple constraints across different modalities. In this work, we introduce CFP-GEN, a novel diffusion language model for Combinatorial Functional Protein G…

Acceleration of Federated Learning with Alleviated Forgetting in Local Training

ICLR 2022poster

Federated learning (FL) enables distributed optimization of machine learning models while protecting privacy by independently training local models on each client and then aggregating parameters on a central server, thereby producing an effective global model. Although a variety of FL algorithms hav…

Reinforced Molecular Optimization with Neighborhood-Controlled Grammars

NeurIPS 2020poster

A major challenge in the pharmaceutical industry is to design novel molecules with specific desired properties, especially when the property evaluation is costly. Here, we propose MNCE-RL, a graph convolutional policy network for molecular optimization with molecular neighborhood-controlled embeddin…
