Optimal vintage factor analysis with deflation varimax

no code implementations16 Oct 2023 Xin Bing, Dian Jin, Yuqian Zhang

Vintage factor analysis is one important type of factor analysis that aims to first find a low-dimensional representation of the original data, and then to seek a rotation such that the rotated low-dimensional representation is scientifically meaningful.

Bilevel Fast Scene Adaptation for Low-Light Image Enhancement

1 code implementation2 Jun 2023 Long Ma, Dian Jin, Nan An, JinYuan Liu, Xin Fan, Risheng Liu

A bilevel learning framework is constructed to endow the scene-irrelevant generality of the encoder towards diverse scenes (i. e., freezing the encoder in the adaptation and testing phases).

Video Text Tracking With a Spatio-Temporal Complementary Model

1 code implementation9 Nov 2021 Yuzhe Gao, Xing Li, Jiajian Zhang, Yu Zhou, Dian Jin, Jing Wang, Shenggao Zhu, Xiang Bai

We leverage a Siamese ComplementaryModule to fully exploit the continuity characteristic of the textinstances in the temporal dimension, which effectively alleviatesthe missed detection of the text instances, and hence ensuresthe completeness of each text trajectory.

Unique sparse decomposition of low rank matrices

1 code implementation NeurIPS 2021 Dian Jin, Xin Bing, Yuqian Zhang

In this paper, we study the problem of seeking a unique decomposition of a low rank matrix $Y\in \mathbb{R}^{p\times n}$ that admits a sparse representation.
