Focusing Condition: Inference-Time Self-Contrastive Steering Elicits Better Conditional Text Embeddings in LLMs

This work proposes an inference-time, plug-and-play Self-Contrastive Steering (SCS) method that constructs unconditional general text embeddings and uses them to refine conditional text embeddings, making them more focused on the target condition.

Dynamic Distribution-Aware Uncertainty Tracking in Vision-Language Representation Learning

A Dynamic Distribution-Aware Uncertainty Quantification framework (DDA-UQ) is proposed that shifts the paradigm from static mapping to a dynamic distribution-aware process and significantly outperforms state-of-the-art methods.

Rethinking BCE Loss for Multi-Label Image Recognition with Fine-Tuning

Class-wise Covariance Regularization is proposed, which aligns the predicted covariance structure of class confidences with the semantic correlations encoded in pretrained text embed-dings with the geometric consistency of the class space throughout fine-tuning, resulting in more stable and interpretable confidence dis...
