Feature Fusion from Head to Tail for Long-Tailed Visual Recognition

1 code implementation12 Jun 2023 Mengke Li, Zhikai Hu, Yang Lu, Weichao Lan, Yiu-ming Cheung, Hui Huang

To rectify this issue, we propose to augment tail classes by grafting the diverse semantic information from head classes, referred to as head-to-tail fusion (H2T).

Adjusting Logit in Gaussian Form for Long-Tailed Visual Recognition

1 code implementation18 May 2023 Mengke Li, Yiu-ming Cheung, Yang Lu, Zhikai Hu, Weichao Lan, Hui Huang

Based on these perturbed features, two novel logit adjustment methods are proposed to improve model performance at a modest computational overhead.

MTFH: A Matrix Tri-Factorization Hashing Framework for Efficient Cross-Modal Retrieval

1 code implementation4 May 2018 Xin Liu, Zhikai Hu, Haibin Ling, Yiu-ming Cheung

More specifically, MTFH exploits an efficient objective function to flexibly learn the modality-specific hash codes with different length settings, while synchronously learning two semantic correlation matrices to semantically correlate the different hash representations for heterogeneous data comparable.
