Convolutional Neural Net Vs MNIST

In previous posts I used a single layer neural network to try and classify hand written digits, with mixed results. Luckily there is a neural network architecture much more suited for this task. Convolutional neural networks are based on the visual cortex and have achieved very low error rates on the MNIST dataset. The Network …

Visualizing how a deep neural network learns

Last weekend I was working through some Tensor Flow tutorials and thought that it would be nice to be able to visualize the weight change over time in a multi layer neural network. For this I will be using the example of a pizza delivery company. Unfortunately I could not find any pizza delivery data …
