LoRAP: Transformer Sub-Layers Deserve Differentiated Structured Compression for Large Language Models

no code implementations15 Apr 2024 Guangyan Li, Yongqiang Tang, Wensheng Zhang

With this regard, we design a mixed compression model, which organically combines Low-Rank matrix approximation And structured Pruning (LoRAP).

Cross-Stream Contrastive Learning for Self-Supervised Skeleton-Based Action Recognition

no code implementations3 May 2023 Ding Li, Yongqiang Tang, Zhizhong Zhang, Wensheng Zhang

Besides, to further exploit the potential of positive pairs and increase the robustness of self-supervised representation learning, we propose a Positive Feature Transformation (PFT) strategy which adopts feature-level manipulation to increase the variance of positive pairs.

Cross-Domain Label Propagation for Domain Adaptation with Discriminative Graph Self-Learning

no code implementations17 Feb 2023 Lei Tian, Yongqiang Tang, Liangchen Hu, Wensheng Zhang

In this paper, we propose a novel domain adaptation method, which infers target pseudo-labels through cross-domain label propagation, such that the underlying manifold structure of two domain data can be explored.

Constrained Maximum Cross-Domain Likelihood for Domain Generalization

no code implementations9 Oct 2022 Jianxin Lin, Yongqiang Tang, JunPing Wang, Wensheng Zhang

Finally, a Constrained Maximum Cross-domain Likelihood (CMCL) optimization problem is deduced, by solving which the joint distributions are naturally aligned.

Mitigating Both Covariate and Conditional Shift for Domain Generalization

no code implementations17 Sep 2022 Jianxin Lin, Yongqiang Tang, JunPing Wang, Wensheng Zhang

Domain generalization (DG) aims to learn a model on several source domains, hoping that the model can generalize well to unseen target domains.

Active Learning with Effective Scoring Functions for Semi-Supervised Temporal Action Localization

no code implementations31 Aug 2022 Ding Li, Xuebing Yang, Yongqiang Tang, Chenyang Zhang, Wensheng Zhang

And the other introduces a new metric based on mutual information between adjacent action proposals and evaluates the informativeness of video samples, named Temporal Context Inconsistency (TCI).

Attentive pooling for Group Activity Recognition

no code implementations31 Aug 2022 Ding Li, Yuan Xie, Wensheng Zhang, Yongqiang Tang, Zhizhong Zhang

However, the existing methods simply employed max/average pooling in this framework, which ignored the distinct contributions of different individuals to the group activity recognition.
