CDEoH: Category-Driven Automatic Algorithm Design With Large Language Models
Yu-Nian Wang, Shen-Huan Lyu, Ning Chen +3
With the rapid advancement of large language models (LLMs), LLM-based heuristic search methods have demonstrated strong capabilities in automated algorithm generation. However, the…
HiDE: Hierarchical Dictionary-Based Entropy Modeling for Learned Image Compression
Haoxuan Xiong, Yuanyuan Xu, Kun Zhu +2
Learned image compression (LIC) has achieved remarkable coding efficiency, where entropy modeling plays a pivotal role in minimizing bitrate through informative priors. Existing me…
Breaking the Prototype Bias Loop: Confidence-Aware Federated Contrastive Learning for Highly Imbalanced Clients
Tian-Shuang Wu, Shen-Huan Lyu, Ning Chen +4
Local class imbalance and data heterogeneity across clients often trap prototype-based federated contrastive learning in a prototype bias loop: biased local prototypes induced by i…
Enhance and Reuse: A Dual-Mechanism Approach to Boost Deep Forest for Label Distribution Learning
Jia-Le Xu, Shen-Huan Lyu, Yu-Nian Wang +4
Label distribution learning (LDL) requires the learner to predict the degree of correlation between each sample and each label. To achieve this, a crucial task during learning is t…
Compressing Model with Few Class-Imbalance Samples: An Out-of-Distribution Expedition
Tian-Shuang Wu, Shen-Huan Lyu, Ning Chen +2
In recent years, as a compromise between privacy and performance, few-sample model compression has been widely adopted to deal with limited data resulting from privacy and security…
Enhance Learning Efficiency of Oblique Decision Tree via Feature Concatenation
Shen-Huan Lyu, Yi-Xiao He, Yanyan Wang +3
Oblique Decision Tree (ODT) separates the feature space by linear projections, as opposed to the conventional Decision Tree (DT) that forces axis-parallel splits. ODT has been prov…
