Prompt Decoupling for Text-to-Image Person Re-identification

no code implementations4 Jan 2024 Weihao Li, Lei Tan, Pingyang Dai, Yan Zhang

In the first stage, we freeze the two encoders from CLIP and solely focus on optimizing the prompts to alleviate domain gap between the original training data of CLIP and downstream tasks.

Key Issues in Wireless Transmission for NTN-Assisted Internet of Things

no code implementations25 Nov 2023 Chenhao Qi, Jing Wang, Leyi Lyu, Lei Tan, Jinming Zhang, Geoffrey Ye Li

The long-distance wireless signal propagation in NTNs leads to severe path loss and large latency, where the accurate acquisition of channel state information (CSI) is another challenge, especially for fast-moving non-terrestrial base stations (NTBSs).

Attention Disturbance and Dual-Path Constraint Network for Occluded Person Re-identification

no code implementations20 Mar 2023 Jiaer Xia, Lei Tan, Pingyang Dai, Mingbo Zhao, Yongjian Wu, Liujuan Cao

To address this issue, we propose a novel transformer-based Attention Disturbance and Dual-Path Constraint Network (ADP) to enhance the generalization of attention networks.

Spectral Aware Softmax for Visible-Infrared Person Re-Identification

no code implementations3 Feb 2023 Lei Tan, Pingyang Dai, Qixiang Ye, Mingliang Xu, Yongjian Wu, Rongrong Ji

Based on the observation and analysis of SA-Softmax, we modify the SA-Softmax with the Feature Mask and Absolute-Similarity Term to alleviate the ambiguous optimization during model training.

Exploring Invariant Representation for Visible-Infrared Person Re-Identification

no code implementations2 Feb 2023 Lei Tan, Yukang Zhang, ShengMei Shen, Yan Wang, Pingyang Dai, Xianming Lin, Yongjian Wu, Rongrong Ji

Cross-spectral person re-identification, which aims to associate identities to pedestrians across different spectra, faces a main challenge of the modality discrepancy.

Dynamic Prototype Mask for Occluded Person Re-Identification

1 code implementation19 Jul 2022 Lei Tan, Pingyang Dai, Rongrong Ji, Yongjian Wu

Although person re-identification has achieved an impressive improvement in recent years, the common occlusion case caused by different obstacles is still an unsettled issue in real application scenarios.

Weighted Neural Tangent Kernel: A Generalized and Improved Network-Induced Kernel

1 code implementation22 Mar 2021 Lei Tan, Shutong Wu, Xiaolin Huang

In this paper, we introduce the Weighted Neural Tangent Kernel (WNTK), a generalized and improved tool, which can capture an over-parameterized NN's training dynamics under different optimizers.

Low Dimensional Landscape Hypothesis is True: DNNs can be Trained in Tiny Subspaces

1 code implementation20 Mar 2021 Tao Li, Lei Tan, Qinghua Tao, Yipeng Liu, Xiaolin Huang

Deep neural networks (DNNs) usually contain massive parameters, but there is redundancy such that it is guessed that the DNNs could be trained in low-dimensional subspaces.

Panoptic Studio: A Massively Multiview System for Social Interaction Capture

1 code implementation9 Dec 2016 Hanbyul Joo, Tomas Simon, Xulong Li, Hao liu, Lei Tan, Lin Gui, Sean Banerjee, Timothy Godisart, Bart Nabbe, Iain Matthews, Takeo Kanade, Shohei Nobuhara, Yaser Sheikh

The core challenges in capturing social interactions are: (1) occlusion is functional and frequent; (2) subtle motion needs to be measured over a space large enough to host a social group; (3) human appearance and configuration variation is immense; and (4) attaching markers to the body may prime the nature of interactions.
