Textual Knowledge Matters: Cross-Modality Co-Teaching for Generalized Visual Class Discovery

no code implementations12 Mar 2024 Haiyang Zheng, Nan Pu, Wenjing Li, Nicu Sebe, Zhun Zhong

In this paper, we study the problem of Generalized Category Discovery (GCD), which aims to cluster unlabeled data from both known and unknown categories using the knowledge of labeled data from known categories.

On each client, GCL builds class-level contrastive learning with both local and global GMMs.

Dynamic Conceptional Contrastive Learning for Generalized Category Discovery

1 code implementation CVPR 2023 Nan Pu, Zhun Zhong, Nicu Sebe

This leads traditional novel category discovery (NCD) methods to be incapacitated for GCD, due to their assumption of unlabeled data are only from novel categories.

Lifelong Person Re-Identification via Adaptive Knowledge Accumulation

1 code implementation CVPR 2021 Nan Pu, Wei Chen, Yu Liu, Erwin M. Bakker, Michael S. Lew

In this work we explore a new and challenging ReID task, namely lifelong person re-identification (LReID), which enables to learn continuously across multiple domains and even generalise on new and unseen domains.

PREPRINT: Comparison of deep learning and hand crafted features for mining simulation data

no code implementations11 Mar 2021 Theodoros Georgiou, Sebastian Schmitt, Thomas Bäck, Nan Pu, Wei Chen, Michael Lew

The output of such simulations, in particular the calculated flow fields, are usually very complex and hard to interpret for realistic three-dimensional real-world applications, especially if time-dependent simulations are investigated.

Dual Gaussian-based Variational Subspace Disentanglement for Visible-Infrared Person Re-Identification

1 code implementation6 Aug 2020 Nan Pu, Wei Chen, Yu Liu, Erwin M. Bakker, Michael S. Lew

To solve the problem, we present a carefully designed dual Gaussian-based variational auto-encoder (DG-VAE), which disentangles an identity-discriminable and an identity-ambiguous cross-modality feature subspace, following a mixture-of-Gaussians (MoG) prior and a standard Gaussian distribution prior, respectively.
