Generalized Category Discovery with Decoupled Prototypical Network

1 code implementation28 Nov 2022 Wenbin An, Feng Tian, Qinghua Zheng, Wei Ding, Qianying Wang, Ping Chen

Furthermore, the coupled training approach prevents these models transferring category-specific knowledge explicitly from labeled data to unlabeled data, which can lose high-level semantic information and impair model performance.

Noise-Tolerant Learning for Audio-Visual Action Recognition

no code implementations16 May 2022 Haochen Han, Qinghua Zheng, Minnan Luo, Kaiyao Miao, Feng Tian, Yan Chen

A noise-tolerant contrastive training phase is performed first to learn robust model parameters unaffected by the noisy labels.

CASS: Towards Building a Social-Support Chatbot for Online Health Community

2 code implementations4 Jan 2021 Liuping Wang, Dakuo Wang, Feng Tian, Zhenhui Peng, Xiangmin Fan, Zhan Zhang, Shuai Ma, Mo Yu, Xiaojuan Ma, Hongan Wang

Chatbots systems, despite their popularity in today's HCI and CSCW research, fall short for one of the two reasons: 1) many of the systems use a rule-based dialog flow, thus they can only respond to a limited number of pre-defined inputs with pre-scripted responses; or 2) they are designed with a focus on single-user scenarios, thus it is unclear how these systems may affect other users or the community.

Modeling e-Learners' Cognitive and Metacognitive Strategy in Comparative Question Solving

no code implementations4 Jun 2019 Feng Tian, Jia Yue, Kuo-Ming Chao, Buyue Qian, Nazaraf Shah, Longzhuang Li, Haiping Zhu, Yan Chen, Bin Zeng, Qinghua Zheng

from "The C Programming Language" course and "What are similarities and differences between packet switching and circuit switching?"

The MUSCLES Treasury Survey. V. FUV Flares on Active and Inactive M Dwarfs

2 code implementations19 Sep 2018 R. O. Parke Loyd, Kevin France, Allison Youngblood, Christian Schneider, Alexander Brown, Renyu Hu, Antígona Segura, Jeffrey Linsky, Seth Redfield, Feng Tian, Sarah Rugheimer, Yamila Miguel, Cynthia S. Froning

The rate and distribution of flares are such that they could dominate the FUV energy budget of M dwarfs, assuming the same distribution holds to flares as energetic as those cataloged by Kepler and ground-based surveys.
