CuMA: Aligning LLMs with Sparse Cultural Values via Demographic-Aware Mixture of Adapters

Ao Sun, Xiaoyu Wang, Zhe Tan +4

As Large Language Models (LLMs) serve a global audience, alignment must transition from enforcing universal consensus to respecting cultural pluralism. We demonstrate that dense mo…

Refine and Purify: Orthogonal Basis Optimization with Null-Space Denoising for Conditional Representation Learning

Jiaquan Wang, Yan Lyu, Chen Li +1

Conditional representation learning aims to extract criterion-specific features for customized tasks. Recent studies project universal features onto the conditional feature subspac…

Keep It on a Leash: Controllable Pseudo-label Generation Towards Realistic Long-Tailed Semi-Supervised Learning

Yaxin Hou, Bo Han, Yuheng Jia +2

Current long-tailed semi-supervised learning methods assume that labeled data exhibit a long-tailed distribution, and unlabeled data adhere to a typical predefined distribution (i.…

DiCaP: Distribution-Calibrated Pseudo-labeling for Semi-Supervised Multi-Label Learning

Bo Han, Zhuoming Li, Xiaoyu Wang +4

Semi-supervised multi-label learning (SSMLL) aims to address the challenge of limited labeled data in multi-label learning (MLL) by leveraging unlabeled data to improve the model's…

ESMC: MLLM-Based Embedding Selection for Explainable Multiple Clustering

Xinyue Wang, Yuheng Jia, Hui Liu +1

Typical deep clustering methods, while achieving notable progress, can only provide one clustering result per dataset. This limitation arises from their assumption of a fixed under…
