WebJan 1, 2012 · Compared with the classical clustering algorithms, co-clustering algorithms have been shown to be more effective in discovering hidden clustering structures in the … WebConfusion matrix. We also evaluated kmeans using confusion matrix. We called the crosstab function. We will give the function original data labels and predicted labels and it makes a confusion matrix. For the class 0, 50 of them get labeled as 0. which means that k-means predicted the labels for setosa as 100% correct.
