Addressing Topic Granularity and Hallucination in Large Language Models for Topic Modelling

no code implementations1 May 2024 Yida Mu, Peizhen Bai, Kalina Bontcheva, Xingyi Song

In this paper, we focus on addressing the issues of topic granularity and hallucinations for better LLM-based topic modelling.

Geometry-aware Line Graph Transformer Pre-training for Molecular Property Prediction

no code implementations1 Sep 2023 Peizhen Bai, Xianyuan Liu, Haiping Lu

Owing to the scarcity of labeled molecules, there has been growing interest in self-supervised learning methods that learn generalizable molecular representations from unlabeled data.

Interpretable bilinear attention network with domain adaptation improves drug-target prediction

2 code implementations3 Aug 2022 Peizhen Bai, Filip Miljković, Bino John, Haiping Lu

Recent deep learning-based methods show promising performance but two challenges remain: (i) how to explicitly model and learn local interactions between drugs and targets for better prediction and interpretation; (ii) how to generalize prediction performance on novel drug-target pairs from different distribution.
