Present-Biased Lobbyists in Linear Quadratic Stochastic Differential Games

no code implementations23 Apr 2023 Ali Lazrak, Hanxiao Wang, Jiongmin Yong

We investigate a linear quadratic stochastic zero-sum game where two players lobby a political representative to invest in a wind turbine farm.

Dont Even Look Once: Synthesizing Features for Zero-Shot Detection

no code implementations18 Nov 2019 Pengkai Zhu, Hanxiao Wang, Venkatesh Saligrama

Zero-shot detection, namely, localizing both seen and unseen objects, increasingly gains importance for large-scale applications, with large number of object classes, since, collecting sufficient annotated data with ground truth bounding boxes is simply not scalable.

Learning Classifiers for Domain Adaptation, Zero and Few-Shot Recognition Based on Learning Latent Semantic Parts

no code implementations25 Jan 2019 Pengkai Zhu, Hanxiao Wang, Venkatesh Saligrama

In computer vision applications, such as domain adaptation (DA), few shot learning (FSL) and zero-shot learning (ZSL), we encounter new objects and environments, for which insufficient examples exist to allow for training "models from scratch," and methods that adapt existing models, trained on the presented training environment, to the new scenario are required.

Person Re-Identification in Identity Regression Space

no code implementations25 Jun 2018 Hanxiao Wang, Xiatian Zhu, Shaogang Gong, Tao Xiang

Most existing person re-identification (re-id) methods are unsuitable for real-world deployment due to two reasons: Unscalability to large population size, and Inadaptability over time.

Zero-Shot Detection

1 code implementation19 Mar 2018 Pengkai Zhu, Hanxiao Wang, Venkatesh Saligrama

While we utilize semantic features during training, our method is agnostic to semantic information for unseen classes at test-time.

Deep Reinforcement Learning Attention Selection for Person Re-Identification

no code implementations10 Jul 2017 Xu Lan, Hanxiao Wang, Shaogang Gong, Xiatian Zhu

Existing person re-identification (re-id) methods assume the provision of accurately cropped person bounding boxes with minimum background noise, mostly by manually cropping.

Human-In-The-Loop Person Re-Identification

no code implementations5 Dec 2016 Hanxiao Wang, Shaogang Gong, Xiatian Zhu, Tao Xiang

Current person re-identification (re-id) methods assume that (1) pre-labelled training data are available for every camera pair, (2) the gallery size for re-identification is moderate.

Highly Efficient Regression for Scalable Person Re-Identification

no code implementations5 Dec 2016 Hanxiao Wang, Shaogang Gong, Tao Xiang

Existing person re-identification models are poor for scaling up to large data required in real-world applications due to: (1) Complexity: They employ complex models for optimal performance resulting in high computational cost for training at a large scale; (2) Inadaptability: Once trained, they are unsuitable for incremental update to incorporate any new data available.
