What’s Neural Networks ??
市面上一堆產品AI、AI的在喊，了解的人，基本上應該都不會去盲從，因為絕大多數都是廣告式AI。 AI 、deep Learn，廣泛的用在廣告用語。其中架構，不外乎 只有 Neural Networks。當然，瞭解之後，千萬別刁難產品推銷業務人員。 Neural...

MNIST MLP – Dropout
減少過度擬合。在深度學習的訓練過程中，Dropout會每次都依據機率丟棄一定比例的神經元不予計算。下面程式，義該Dropout層每次訓練時要丟棄25%的神經元。
Keras – MNIST MLP
MNIST 的圖片是 28 像素 x 28 像素，每一張圖片就可以用 28 x 28 = 784 個數字來紀錄，因此 print(x_train.shape) 的輸出告訴我們有 48000 張訓練圖片，每張圖片都有 784 個數字；而...
