// A header file to get you set going with Intel SIMD instrinsic programming. 
// All necessary header files are inlucded for SSE2, SSE41, and AVX2
// Macros make the intrinsics easier to read and  generic so you can compile to 
// SSE2 or AVX2 with the flip of a #define


#define SSE2  //indicates we want SSE2
#define SSE41 //indicates we want SSE4.1 instructions (floor and blend is available)
#define AVX2 //indicates we want AVX2 instructions (double speed!)

""" Deep Auto-Encoder implementation
	
	An auto-encoder works as follows:

	Data of dimension k is reduced to a lower dimension j using a matrix multiplication:
	softmax(W*x + b)  = x'
	
	where W is matrix from R^k --> R^j

	A reconstruction matrix W' maps back from R^j --> R^k
