( Learning_Rate = 5 ) Type in a number from 10 to 90 (ex. 43, or 63), and it will try to find your number! At first, it will be bad, but it will actually learn, and catch on. Press Space to explain the neural network Click the flag to try a different number. 16 hrs+ research 4+ hrs to make The reason that it took so long is not actually the code. You have to understand neural networks and all their different formulas like sigmoids (1/1+e^-x), and (w1*x1+w2*x2).
