A Generalist Cross-Domain Molecular Learning Framework for Structure-Based Drug Discovery

no code implementations6 Mar 2025 Yiheng Zhu, Mingyang Li, Junlong Liu, Kun fu, JianSheng Wu, Qiuyi Li, Mingze Yin, Jieping Ye, Jian Wu, Zheng Wang

To fill this gap, we propose a general-purpose foundation model named BIT (an abbreviation for Biomolecular Interaction Transformer), which is capable of encoding a range of biochemical entities, including small molecules, proteins, and protein-ligand complexes, as well as various data formats, encompassing both 2D and 3D structures.

Self-Adaptive Reconstruction with Contrastive Learning for Unsupervised Sentence Embeddings

no code implementations23 Feb 2024 Junlong Liu, Xichen Shang, Huawen Feng, Junhao Zheng, Qianli Ma

However, due to the token bias in pretrained language models, the models can not capture the fine-grained semantics in sentences, which leads to poor predictions.

Preserving Commonsense Knowledge from Pre-trained Language Models via Causal Inference

2 code implementations19 Jun 2023 Junhao Zheng, Qianli Ma, Shengjie Qiu, Yue Wu, Peitian Ma, Junlong Liu, Huawen Feng, Xichen Shang, Haibin Chen

Intriguingly, the unified objective can be seen as the sum of the vanilla fine-tuning objective, which learns new knowledge from target data, and the causal objective, which preserves old knowledge from PLMs.

MPC: Multi-View Probabilistic Clustering

no code implementations CVPR 2022 Junjie Liu, Junlong Liu, Shaotian Yan, Rongxin Jiang, Xiang Tian, Boxuan Gu, Yaowu Chen, Chen Shen, Jianqiang Huang

Despite the promising progress having been made, the two challenges of multi-view clustering (MVC) are still waiting for better solutions: i) Most existing methods are either not qualified or require additional steps for incomplete multi-view clustering and ii) noise or outliers might significantly degrade the overall clustering performance.
