International Conference on Learning Representations (ICLR) 2024

Recent studies in protein design achieve competitive performance but often overlook predictive confidence, broad protein space coverage, and common protein knowledge. To address this, we propose KW-Design, a method that refines low-quality residues using a knowledge-aware module and accelerates training with a memory-retrieval mechanism

Advances in Neural Information Processing Systems (Neurips) 2023

Protein inverse folding has gained attention recently, but existing methods are limited by the CATH dataset, recovery metric, and lack of a unified benchmarking framework. To address this, we propose ProteinBench, a comprehensive benchmark integrating diverse protein design tasks, models, and evaluation metrics, enabling thorough comparisons and inspiring future advancements.

Arxiv 2023

Predicting protein stability changes from single-point mutations remains a significant challenge, hindered by feature extraction complexity and limited experimental data. Leveraging ESM-based large language models, we propose an efficient method integrating sequence and structural features to predict thermostability changes, supported by a carefully curated dataset to ensure fair model comparison.

Electronics 2022

Mobile Edge Computing (MEC) addresses growing demands for high-quality computing, but traditional resource allocation faces challenges like privacy risks, further complicated by blockchain-enabled MEC systems. To tackle this, we propose a blockchain-based MEC architecture with a novel Proof of Learning (PoL) consensus, optimizing resource allocation using an A3C algorithm enhanced with temporal convolutional networks (TCN) for faster, more stable convergence.
