Are you trying to run the script from inside the ZIP-file, without extracting it? 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.

Find the treasures in MATLAB Central and discover how the community can help you! Description class = classify (sample,training,group) classifies each row of the data in sample into one of the groups in training. sample and training must be matrices with the same number of columns. group is a grouping variable for training.
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. That way you don't need to mess with MATLAB's original source. scripts / matlab / knnclassify.m Go to file Go to file T; Go to line L; Copy path Cannot retrieve contributors at this time.
I am trying to implement knnclassify in matlab for fisheriris data set and try to get the confusion matrix for it. Below is the code for matlab implementation of knnclassify. I am unable to understand how to incorporate the fisheriris datase in this code. and how to calculate the confusion matrix.

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. și k = 5.

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.
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.

Hand_Gesture_Recognition. This calls knnclassify on MATLAB and organizes data from Virtual Motion Labs' Data Glove Lite. The goal of this project is to test the robustness of k-nearest-neighbor algorithm and discover how the training basis, the quantity of samples, and the relationship of finger flexibility and hand rotation affect the accuracy of gesture recognition. modifying results of knnclassify.
