AMU-Tuning: Effective Logit Bias for CLIP-based Few-shot Learning

1 code implementation13 Apr 2024 Yuwei Tang, Zhenyi Lin, Qilong Wang, Pengfei Zhu, QinGhua Hu

To this end, we disassemble three key components involved in computation of logit bias (i. e., logit features, logit predictor, and logit fusion) and empirically analyze the effect on performance of few-shot classification.

Selective Learning: Towards Robust Calibration with Dynamic Regularization

no code implementations13 Feb 2024 Zongbo Han, Yifeng Yang, Changqing Zhang, Linjun Zhang, Joey Tianyi Zhou, QinGhua Hu, Huaxiu Yao

The objective can be understood as seeking a model that fits the ground-truth labels by increasing the confidence while also maximizing the entropy of predicted probabilities by decreasing the confidence.

Exploring Diverse Representations for Open Set Recognition

1 code implementation12 Jan 2024 Yu Wang, Junxian Mu, Pengfei Zhu, QinGhua Hu

We show that the differences in attention maps can lead to diverse representations so that the fused representations can well handle the open space.
