#1. Neural network Demand Prediction 예시 : 어떤 티셔츠가 top seller 티셔츠가 될 것인가 ? → input : x = price , shipping cost, marketing, material ... → output : y = yes or no (binary:sigmoid) → activation : f(x) = 1 / 1+np.exp(-(wx+b)) Neural network에서 이를 사용하게 될 경우 → input layer : vector x [price,shipping cost, marketing, material] and vector y [1,1,0,1,...n] → layer1(hidden layer) : input layer와 fully connect..
