Fractional Order Iteration for Gradient Descent Method Based on Event-Triggered Mechanism
《Journal of Systems Science & Complexity》2023年第5期1927-1948,共22页LU Jiajie WANG Yong FAN Yuan 
supported by the National Natural Science Foundation of China under Grant No.61973291。
In this work,a novel gradient descent method based on event-triggered strategy has been proposed,which involves integer and fractional order iteration.Firstly,the convergence of integer order iterative optimization me...

Parametric Narrow-Band InISAR 3D Imaging Based on Compressed Sensing被引量：1
《Chinese Journal of Electronics》2020年第3期508-514,共7页WANG Baoping ZHANG Yan FANG Yang SONG Zuxun 
This work is supported by the National Natural Science Foundation of China(No.61472324).
For muti-scatter point target and undersampled data,tradintional imaging method has a poor precision for imaging result and spin angular velocity.In view of the above problems,this paper proposes a narrow-band Interfe...

Multiframe Blind Super Resolution Imaging Based on Blind Deconvolution
《Transactions of Tianjin University》2016年第4期358-366,共9页元伟 张立毅 
Supported by the National Natural Science Foundation of China(No.61340034);the Research Program of Application Foundation and Advanced Technology of Tianjin(No.13JCYBJC15600)
As an ill-posed problem, multiframe blind super resolution imaging recovers a high resolution image from a group of low resolution images with some degradations when the information of blur kernel is limited. Note tha...

Research on the iterative method for model updating based on the frequency response function被引量：3
《Acta Mechanica Sinica》2012年第2期450-457,共8页Wei-Ming Li Jia-Zhen Hong 
supported by the Key Project of the National Natural Science Foundation of China (11132007)
Model reduction technique is usually employed in model updating process. In this paper, a new model updat- ing method named as cross-model cross-frequency response function （CMCF） method is proposed and a new iterat...

An iterative modified kernel based on training data被引量：2
《Applied Mathematics and Mechanics(English Edition)》2009年第1期121-128,共8页周志祥 韩逢庆 
Project supported by the National Natural Science Foundation of China (No. 50578168);the Natural Science Foundation of CQ CSTC (No. 2007BB2396)
To improve performance of a support vector regression, a new method for a modified kernel function is proposed. In this method, information of all samples is included in the kernel function with conformal mapping. Thu...
