 There are three custom operators included in this sample: Relu, NoisyRelu and Debug.
-The Relu custom operator is replacing an existing operator while NoisyRelu and Debug are new operators.
 
 Relu transforms the input data using the function max(0, input). Noisy Relu is a variant of Relu which introduces Guassian noise.
