Memory Enhanced Global-Local Aggregation for Video Object Detection

2 code implementations CVPR 2020 Yihong Chen, Yue Cao, Han Hu, Li-Wei Wang

We argue that there are two important cues for humans to recognize objects in videos: the global semantic information and the local localization information.

You Impress Me: Dialogue Generation via Mutual Persona Perception

1 code implementation ACL 2020 Qian Liu, Yihong Chen, Bei Chen, Jian-Guang Lou, Zixuan Chen, Bin Zhou, Dongmei Zhang

Despite the continuing efforts to improve the engagingness and consistency of chit-chat dialogue systems, the majority of current work simply focus on mimicking human-like responses, leaving understudied the aspects of modeling understanding between interlocutors.

RepPoints V2: Verification Meets Regression for Object Detection

1 code implementation NeurIPS 2020 Yihong Chen, Zheng Zhang, Yue Cao, Li-Wei Wang, Stephen Lin, Han Hu

Though RepPoints provides high performance, we find that its heavy reliance on regression for object localization leaves room for improvement.

HDI-Forest: Highest Density Interval Regression Forest

1 code implementation24 May 2019 Lin Zhu, Jiaxing Lu, Yihong Chen

By seeking the narrowest prediction intervals (PIs) that satisfy the specified coverage probability requirements, the recently proposed quality-based PI learning principle can extract high-quality PIs that better summarize the predictive certainty in regression tasks, and has been widely applied to solve many practical problems.

Learning-to-Ask: Knowledge Acquisition via 20 Questions

no code implementations22 Jun 2018 Yihong Chen, Bei Chen, Xuguang Duan, Jian-Guang Lou, Yue Wang, Wenwu Zhu, Yong Cao

Almost all the knowledge empowered applications rely upon accurate knowledge, which has to be either collected manually with high cost, or extracted automatically with unignorable errors.

A Domain Generalization Perspective on Listwise Context Modeling

no code implementations12 Feb 2019 Lin Zhu, Yihong Chen, Bowen He

As one of the most popular techniques for solving the ranking problem in information retrieval, Learning-to-rank (LETOR) has received a lot of attention both in academia and industry due to its importance in a wide variety of data mining applications.
