hi all, I have a doubt regarding knn classification...I have 1x1200 features for every test and train samples. And the length (number of images)of train was 500. Number of classes i need to classify is 10(subimages=10, number of sets=50 in train) How to classify this using knn classification?I know dat will be given as knnclassify(train,sample,group) But it shows error that displays Group have the length that equal to the rows of train....I couldn't understand ...Please provide me the answer....
