Vanishing Gradient Check

Problem

A point is flagged as a vanishing-gradient candidate when the Euclidean norm of the gradient falls below a tolerance.

Given the gradient vector and the tolerance, return True when the norm is strictly less than the tolerance.

Hint

Compute the norm first and compare with a strict inequality.

case 1

in: [[1e-8,1e-8],0.000001]

expected: true

case 2

in: [[1,1],0.5]

expected: false

case 3

in: [[0,0],0]

expected: false
