Publication number: 20230351267Abstract: A method for constructing a support vector machine of a nonparallel structure is provided. On the basis of a traditional parallel support vector machine (SVM), a least square term of samples is added, an additional empirical risk minimization term and an offset constraint term are added to an original optimization problem, so as to obtain two nonparallel hyperplanes respectively, and a new nonparallel support vector machine with additional empirical risk minimization is formed. The method includes: preprocessing data, solving a Lagrange multiplier of a positive-class hyperplane, solving a Lagrange multiplier of a negative-class hyperplane, solving parameters of positive-class and negative-class hyperplanes, and determining a class of a new data point. Through the new method, a new nonparallel vector machine algorithm is proposed to further improve classification accuracy of hyperspectral images on the basis of the algorithm itself, so as to obtain better classification performance.Type: ApplicationFiled: September 2, 2022Publication date: November 2, 2023Applicant: Dalian Minzu UniversityInventors: Liguo WANG, Guangxin LIU, Ying XIAO, Danfeng LIU, Haitao LIU

Patent number: 9786469Abstract: A grid assembly for cryo-electron microscopy may be fabricated using standard nanofabrication processes. The grid assembly may comprise two support members, each support member comprising a silicon substrate coated with an electron-transparent silicon nitride layer. These two support members are positioned together with the silicon nitride layers facing each other with a rigid spacer layer disposed therebetween. The rigid spacer layer defines one or more chambers in which a biological sample may be provided and fast frozen with a high degree of control of the ice thickness.Type: GrantFiled: August 10, 2016Date of Patent: October 10, 2017Assignee: University of WashingtonInventor: Liguo Wang
