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. Question: Tag: matlab,image-processing,classification,pattern-recognition,knn I use knn classifier to classify images according to their writers (problem of writer recognition). I worked on a given database that contains 150 images with 100 images for training and 50 images for testing. Question: Hi I Need A Clear Explanation For This Matlab Code In Detalis Please Function OutClass = Knnclassify(sample, TRAIN, Group, K, Distance,rule,base This MATLAB function creates a cross-validated (partitioned) model from mdl, a fitted KNN classification model.

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). I'm having problems in understanding how K-NN classification works in MATLAB.´ Here's the problem, I have a large dataset (65 features for over 1500 subjects) and its respective classes' label (0 or 1). knnclassify(test_data,train_data,train_label,numberoflabel,‘cosine’,‘random’); main function. 1.CLASS = KNNCLASSIFY(SAMPLE,TRAINING,GROUP) 标号和训练数据必须有相同的行数；训练数据和测试数据必须有相同的列；函数对于无效值或者空值会作为丢失值或者忽略这一行。 how can I convert knnclassify to fitcknn.

I'm using knnclassify to do a kNN classification in Matlab and it's working well. Now, I need to know the distances to the neighbors and it seems that knnsearch funcion gives me that.

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.
