Project load data from MNIST Database coded files to PC memory. MNIST Database I used to verify working of neural network on real-world data. The MNIST database of handwritten digits, has a training set of 60,000 examples, and a test set of 10,000 examples.

MnistDatabase single digit it is grayscale image 28x28 pixels. Pixel value 0-255 is scaled to [-1;1], input data width is equal 28x28=784, output data width is equal 10 (digits 0,1,2,3,9). Output signal is coded as one-hot
