matlab 함수나 사용자가 직접 정의하는 함수의 경우, 이에 대한 함수 핸들을 점수 변환에 사용하십시오. 함수 핸들은 행렬(원래 점수)을 받아 동일한 크기의 행렬(변환된 점수)을 반환합니다.

This MATLAB function returns a k-nearest neighbor classification model based on the input variables (also known as predictors, features, or attributes) in the table Tbl and output (response) Tbl.ResponseVarName. ClassificationKNN is a nearest-neighbor classification model in which you can alter both the distance metric and the number of nearest neighbors. Because a ClassificationKNN classifier stores training data, you can use the model to compute resubstitution predictions. This is a matlab built in function called knnclassify, which is primarily used to identify the nearest neighbour of a data in matrix. I am currently working on matlab and I am new to it. I would like to know how do i average the results from the folds (or otherwise combined) to produce a single estimation.

I would like to know how do i average the results from the folds (or otherwise combined) to produce a single estimation. My dataset has 2 class labels +1 and -1. and k=5. I use the knnclassify() method in matlab in order to perform cross validation. Kindly help!

That won't work. Extract the files to a directory, make the files in that directory accessible to MATLAB (making it your current directory or adding it to the MATLAB path), and then you should be able to run the script.

### I use the KNNclassify function with K=5 and Euclidean distance. Input and output are the same as with the ANN exmaple. I see that can use as you said Bagging or stacking, I may try do both since Matlab has already a ready-to-use function for both.

Is it a 1 by 6 array? I still don't think that would work, because even if it were, you're still giving just 2 dimensions to Test instead of 7. În prezent, lucrez la MATLAB și sunt nou în asta.
