I try to construct the matrix to test with DNN. but I have a problem;
I have vectors that will vary in size from 200 columns to 1200 columns. Each vector represents the characteristic of a handwritten word (5000mot). what to do so that I can normalize vectors for use with RBM and DBN.
for MNIST it does not pose a problem because the images are the same size 28 * 28 which gives us 784 columns network input.
I hope I find the solution.
Thank you for your cooperation.
