Alternatively, use the model to classify new observations using the predict method. 2013-03-15 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. 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!

Description 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. The knnclassify () function uses the k-nearest neighbours classification algorithm to perform classification.
