Parameter Update Relative Change

Problem

The relative parameter change is ||w_new - w_old|| / max(||w_old||, eps).

Given the two parameter vectors and eps, return the relative change.

Hint

Use the Euclidean norms of the update and of the old parameters.

case 1

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

expected: 1

case 2

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

expected: 0

case 3

in: [[0,0],[3,4]]

expected: 5000000000000
