Mind the Gap: Understanding the Modality Gap in Multi-modal Contrastive Representation Learning

no code implementations3 Mar 2022 Weixin Liang, Yuhui Zhang, Yongchan Kwon, Serena Yeung, James Zou

Our systematic analysis demonstrates that this gap is caused by a combination of model initialization and contrastive learning optimization.

Language Models as Recommender Systems: Evaluations and Limitations

no code implementations NeurIPS Workshop ICBINB 2021 Yuhui Zhang, Hao Ding, Zeren Shui, Yifei Ma, James Zou, Anoop Deoras, Hao Wang

Pre-trained language models (PLMs) such as BERT and GPT learn general text representations and encode extensive world knowledge; thus, they can be efficiently and accurately adapted to various downstream tasks.

Collision dominated, ballistic, and viscous regimes of terahertz plasmonic detection by graphene

no code implementations21 Dec 2020 Yuhui Zhang, Michael S. Shur

When the kinematic viscosity ({\nu}) is above a certain critical viscosity value, {\nu}NR, the plasmonic FETs always operates in the viscous non-resonant regime regardless of channel length (L).

Enhancing Transformer with Sememe Knowledge

no code implementations WS 2020 Yuhui Zhang, Chenghao Yang, Zhengping Zhou, Zhiyuan Liu

While large-scale pretraining has achieved great success in many NLP tasks, it has not been fully studied whether external linguistic knowledge can improve data-driven models.

Inducing Grammar from Long Short-Term Memory Networks by Shapley Decomposition

no code implementations ACL 2020 Yuhui Zhang, Allen Nie

The principle of compositionality has deep roots in linguistics: the meaning of an expression is determined by its structure and the meanings of its constituents.

Jiuge: A Human-Machine Collaborative Chinese Classical Poetry Generation System

no code implementations ACL 2019 Guo Zhipeng, Xiaoyuan Yi, Maosong Sun, Wenhao Li, Cheng Yang, Jiannan Liang, Huimin Chen, Yuhui Zhang, Ruoyu Li

By exposing the options of poetry genres, styles and revision modes, Jiuge, acting as a professional assistant, allows constant and active participation of users in poetic creation.

Large-scale Generative Modeling to Improve Automated Veterinary Disease Coding
