Hamming Loss

Problem

Compute the Hamming loss for a multilabel matrix: the fraction of entries where y_true and y_pred disagree.

Empty input returns 0.0.

Hint

Count all mismatched label entries and divide by the total number of entries.

case 1

in: [[[1,0,1],[0,1,0]],[[1,1,1],[0,1,1]]]

expected: 0.3333333333333333

case 2

in: [[[1,0],[0,1]],[[1,0],[0,1]]]

expected: 0

case 3

in: [[[1,1]],[[0,0]]]

expected: 1

case 4

in: [[],[]]

expected: 0
