Prediction Agreement Rate

Problem

Compute the fraction of samples where two prediction lists agree.

Empty input returns 0.0.

Hint

Agreement rate is the pairwise accuracy between two models.

case 1

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

expected: 0.6666666666666666

case 2

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

expected: 1

case 3

in: [[1],[0]]

expected: 0

case 4

in: [[],[]]

expected: 0
