Yes, I've thought about this as well. 

CalculateHalfInputs is the expensive function, and the function is
unfortunately two-sided, so it's not possible to do one-sided caching
which would be very efficient. 

Another idea would be to do some one-sided caching storing the first
matrix-vector multiply inside the neural net evaluation.
