Multi-scale Alternated Attention Transformer for Generalized Stereo Matching

no code implementations6 Aug 2023 Wei Miao, Hong Zhao, Tongjia Chen, Wei Huang, Changyan Xiao

Recent stereo matching networks achieves dramatic performance by introducing epipolar line constraint to limit the matching range of dual-view.

How and what to learn:The modes of machine learning

no code implementations28 Feb 2022 Sihan Feng, Yong Zhang, Fuming Wang, Hong Zhao

We consider weights in pathways that link neurons longitudinally from input neurons to output neurons, or simply weight pathways, as the basic units for understanding a neural network, and decompose a neural network into a series of subnetworks of such weight pathways.

Inferring Global Dynamics Using a Learning Machine

no code implementations28 Sep 2020 Hong Zhao

It is found that following an appropriate training strategy that monotonously decreases the cost function, the learning machine in different training stage can mimic the system at different parameter set.

Deep Learning System to Screen Coronavirus Disease 2019 Pneumonia

no code implementations21 Feb 2020 Xiaowei Xu, Xiangao Jiang, Chunlian Ma, Peng Du, Xukun Li, Shuangzhi Lv, Liang Yu, Yanfei Chen, Junwei Su, Guanjing Lang, Yongtao Li, Hong Zhao, Kaijin Xu, Lingxiang Ruan, Wei Wu

We found that the real time reverse transcription-polymerase chain reaction (RT-PCR) detection of viral RNA from sputum or nasopharyngeal swab has a relatively low positive rate in the early stage to determine COVID-19 (named by the World Health Organization).

Inferring Global Dynamics of a Black-Box System Using Machine Learning

no code implementations10 May 2019 Hong Zhao

We present that, instead of establishing the equations of motion, one can model-freely reveal the dynamical properties of a black-box system using a learning machine.

Copy the dynamics using a learning machine

no code implementations24 Jul 2017 Hong Zhao

Trained by a set of input-output responses or a segment of time series of a black system, a learning machine can be served as a copy system to mimic the dynamics of various black systems.

A General Theory for Training Learning Machine

no code implementations23 Apr 2017 Hong Zhao

The principle of learning, the role of the a prior knowledge, the role of neuron bias, and the basis for choosing neural transfer function and cost function, etc., are still far from clear.

Image Fusion With Cosparse Analysis Operator

no code implementations18 Apr 2017 Rui Gao, Sergiy A. Vorobyov, Hong Zhao

In our approach, we formulate the multi-focus image fusion problem in terms of an analysis sparse model, and simultaneously perform the restoration and fusion of multi-focus images.
