Gradient-Aware Logit Adjustment Loss for Long-tailed Classifier

1 code implementation14 Mar 2024 Fan Zhang, Wei Qin, Weijieying Ren, Lei Wang, Zetong Chen, Richang Hong

Additionally, We find that most of the solutions to long-tailed problems are still biased towards head classes in the end, and we propose a simple and post hoc prediction re-balancing strategy to further mitigate the basis toward head class.

Analyzing and Reducing Catastrophic Forgetting in Parameter Efficient Tuning

1 code implementation29 Feb 2024 Weijieying Ren, Xinlong Li, Lei Wang, Tianxiang Zhao, Wei Qin

Through extensive experiments, we uncover the mode connectivity phenomenon in the LLMs continual learning scenario and find that it can strike a balance between plasticity and stability.

EsaCL: Efficient Continual Learning of Sparse Models

no code implementations11 Jan 2024 Weijieying Ren, Vasant G Honavar

A key challenge in the continual learning setting is to efficiently learn a sequence of tasks without forgetting how to perform previously learned tasks.

T-SaS: Toward Shift-aware Dynamic Adaptation for Streaming Data

no code implementations5 Sep 2023 Weijieying Ren, Tianxiang Zhao, Wei Qin, Kunpeng Liu

Discovering the shifted behaviors and the evolving patterns underlying the streaming data are important to understand the dynamic system.

Graph Relation Aware Continual Learning

no code implementations16 Aug 2023 Qinghua Shen, Weijieying Ren, Wei Qin

Learning a single model could loss discriminative information for each graph task while the model expansion scheme suffers from high model complexity.

Mitigating Popularity Bias in Recommendation with Unbalanced Interactions: A Gradient Perspective

no code implementations31 Oct 2022 Weijieying Ren, Lei Wang, Kunpeng Liu, Ruocheng Guo, Lim Ee Peng, Yanjie Fu

We present a gradient perspective to understand two negative impacts of popularity bias in recommendation model optimization: (i) the gradient direction of popular item embeddings is closer to that of positive interactions, and (ii) the magnitude of positive gradient for popular items are much greater than that of unpopular items.

Semi-supervised Drifted Stream Learning with Short Lookback

no code implementations25 May 2022 Weijieying Ren, Pengyang Wang, Xiaolin Li, Charles E. Hughes, Yanjie Fu

In many scenarios, 1) data streams are generated in real time; 2) labeled data are expensive and only limited labels are available in the beginning; 3) real-world data is not always i. i. d.
