The samples from A that were not selected (every time I have two that are left out), I want to store them separately. What command should I use to separate the 2 that were not selected and to create for them a new array? Because I also want to...
先选择Xnew_ks_notsel_ks_sel,然后选择Select from array,再选idx_validation,再点击Invert就会反向选择,意思就是把Xnew_ks_notsel_ks_sel剩下的数据全选上。 To choose the samples of prediction, select the matrix Xnew_ks_notsel_ks_sel again in the “Data matrices in the workspace” group. Use ...
Open in MATLAB Online Hi guys. I need a little help from you Matlab experts. I have a cell array (Names) with a list of 14 different names. Then I have a 15x3 matrix (Selection) with some random numbers from 0-14. Now what I want to do is use each row in the "selection" mat...
All active set selection methods (except "random") require the storage of an n-by-m matrix, where m is the size of the active set and n is the number of observations. Example: ActiveSetMethod="entropy" RandomSearchSetSize— Random search set size 59 (default) | integer value Random sea...
sequentialfsreturns the structure arrayhistorywith two fields (InandCrit) containing information about the feature selection process. TheInfield contains a logical matrix where rowiindicates the features selected at iterationi. Atrue(logical1) entry in a row indicates that the corresponding feature is ...
