  • Normalization formulas for neural networks

    Hello everybody,

    today I want to write a short note about normalization for neural networks. 

    So, first goes formula how to normalize input in range [0, 1] ( taken from here ): 

    Another good for me example is going below ( taken from here ):

    p = [4 4 3 3 4;

    2 1 2 1 1;

    2 2 2 4 2];

    a = min(p(:));

    b = max(p(:));

    ra = 0.9;

    rb = 0.1;

    pa = (((ra-rb) * (p - a)) / (b - a)) + rb;

    In this example ra stands for maximum value of range, rb stands for minimum value of range that we want to make.
