Mindray Beijing Research Institute
Zhiwei SHI was born in Luoyang, a beautiful city in central China.
In 1998, Zhiwei SHI became a university student at Zhengzhou University, and received Bachelor Degree in Electric Automatization in 2002. In the same year, Zhiwei SHI began his master degree program at Dalian Univ. of Technology, and in 2004 he became a PHD Candidate at Intelligent Control and Information Processing Research Group (ICIP Group) in Dalian Univ. of Technology.
In the summer of 2008, he became a research and development engineer at Mindray Beijing Research Institute, and now his work and research are focused on medical ultrasound imaging.

Drop me any comments about the new algorithm
γ–C plane in a static reservoir (Software Download)
The proposed method inherits the basic idea from support vector echo-state machines(SVESMs), but applies for static nonlinear regression estimation problem. Based on the experience of echo state networks(ESN) and extreme learning machine(ELM), the global scaling parameter γ and the regularization parameter C are used to characterize a reservoir, and the proper reservoir is identified on the γ-C plane.
The left figure is the “γ-C” plane in a static reservoir for the Abalone regression datasets.
