Order-preserving Consistency Regularization for Domain Adaptation and Generalization

1 code implementation ICCV 2023 Mengmeng Jing, XianTong Zhen, Jingjing Li, Cees Snoek

To alleviate this problem, data augmentation coupled with consistency regularization are commonly adopted to make the model less sensitive to domain-specific attributes.

Knowledge-Aware Prompt Tuning for Generalizable Vision-Language Models

no code implementations ICCV 2023 Baoshuo Kan, Teng Wang, Wenpeng Lu, XianTong Zhen, Weili Guan, Feng Zheng

Pre-trained vision-language models, e. g., CLIP, working with manually designed prompts have demonstrated great capacity of transfer learning.

Learning Variational Neighbor Labels for Test-Time Domain Generalization

no code implementations8 Jul 2023 Sameer Ambekar, Zehao Xiao, Jiayi Shen, XianTong Zhen, Cees G. M. Snoek

We formulate the generalization at test time as a variational inference problem by modeling pseudo labels as distributions to consider the uncertainty during generalization and alleviate the misleading signal of inaccurate pseudo labels.

EMO: Episodic Memory Optimization for Few-Shot Meta-Learning

no code implementations8 Jun 2023 Yingjun Du, Jiayi Shen, XianTong Zhen, Cees G. M. Snoek

By learning to retain and recall the learning process of past training tasks, EMO nudges parameter updates in the right direction, even when the gradients provided by a limited number of examples are uninformative.

MetaModulation: Learning Variational Feature Hierarchies for Few-Shot Learning with Fewer Tasks

1 code implementation17 May 2023 Wenfang Sun, Yingjun Du, XianTong Zhen, Fan Wang, Ling Wang, Cees G. M. Snoek

To account for the uncertainty caused by the limited training tasks, we propose a variational MetaModulation where the modulation parameters are treated as latent variables.

CageViT: Convolutional Activation Guided Efficient Vision Transformer

no code implementations17 May 2023 Hao Zheng, Jinbao Wang, XianTong Zhen, Hong Chen, Jingkuan Song, Feng Zheng

Recently, Transformers have emerged as the go-to architecture for both vision and language modeling tasks, but their computational efficiency is limited by the length of the input sequence.
