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. What is repmat(i,n,1)? 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. Aș dori să știu cum obțin media rezultatelor din fold (sau combinate altfel) pentru a produce o singură estimare. Setul de date are 2 etichete de clasă +1 și -1.

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.

I wish now to classify a sample of data, say a set of co-ordinates and classify it against two or more training data sets, choosing one of the two training sets (classifying by matrix rather than row). Getting the distances from classes in knnclassify. Learn more about knnclassify Statistics and Machine Learning Toolbox You use the more modern fitcknn, which is good, but you then pass the resulting model to the older knnclassify as if the model is training data. To classify your test data these days you should be using predict() on the model returned by fitcknn.

2020-04-22 tl;dr: You can do it but you'll have to modify the knnclassify source if you want to do this. Alternatively, you can see what knnclassify is doing, then just pull out the relevant calls that pertain to just your case and place your custom histogram intersection method accordingly, create a new file and just run this file.
