Forward() public method

This function encodes all the layers of the network into given commandBuffer, it calls subroutines for each piece of the network Returns: Guess of the network as to what the digit is as UInt
public Forward ( MPSImage inputImage = null, int imageNum = 9999, int correctLabel = 10 ) : uint
inputImage MPSImage Image coming in on which the network will run
imageNum int If the test set is being used we will get a value between 0 and 9999 for which of the 10,000 images is being evaluated
correctLabel int The correct label for the inputImage while testing
return uint
