k means - Normalising Data to use Cosine Distance in Kmeans (Python) -


i solving problem have use cosine distance similarity measure kmeans clustering. however, standard kmeans clustering package (from sklearn package) uses euclidean distance standard, , not allow change this.

therefor understanding normalising original dataset through the code below. can run kmeans package (using euclidean distance) , same if had changed distance metric cosine distance?

from sklearn import preprocessing  # normalise existing x x_norm = preprocessing.normalize(x)  km2 = cluster.kmeans(n_clusters=5,init='random').fit(x_norm)

please let me know if mathematical understanding of incorrect?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
