This is the function to find the closest prototype vector for a given vector:def find_closest(in_vector,proto_vectors): closest = None closest_distance = 99999 for p_v in proto_vectors: distance = euclidean_distances(in_vector,p_v.p_vector) if distance < closest_distance: closest_distance = distance closest = p_v return closest

A convenient function to find the class ID of the closest prototype vector is as follows:def find_class_id(test_vector,p_vectors): return find_closest(test_vector,p_vectors).class_id
