Neural Net Vs MNIST (Part 2)

In part 1 we trained a 1 layer neural net to predict the correct digit when shown a 28×28 gray scale image of a handwritten digit. After several thousand training steps the network eventually managed to get an average test error of ~10%. In this post I would like to look under the hood of …

Neural Net Vs MNIST (Part 1)

Nearly every machine learning blog inevitably does a post on the MNIST data set. I don’t want to break with tradition…so here is mine. What is MNIST ? MNIST is a data set containing 60000 images of handwritten digits (0-9) along with a label indicating what digit the image represents. Each image is 28×28 pixels …
