explain how backpropagation works, but few that include an example with actual numbers. This post is my attempt to explain how it works with a concrete example that folks can compare their own calculations to in https://mattmazur.com/2015/03/17/a-step-by-step-backpropagation-example/ order to ensure they understand backpropagation correctly. If this kind of thing interests you, you should sign up for my newsletter where I post about AI-related projects that I'm working on. Backpropagation in Python You can play around with a Python script that I wrote that implements the backpropagation algorithm in this Github repo. Backpropagation Visualization For an interactive visualization showing a neural network as it learns, check out my back propagation Neural Network visualization. Additional Resources If you find this tutorial useful and want to continue learning about neural networks and their applications, I highly recommend checking out Adrian Rosebrock's excellent tutorial on Getting Started with Deep Learning and Python. Overview For this tutorial, we're going to use a neural network with two inputs, two hidden neurons, two output neurons. Additionally, the hidden and output neurons will include a back propagation algorithm bias. Here's the basic structure: In order to have some numbers to work with, here are the initial weights, the biases, and training inputs/outputs: The goal of backpropagation is to optimize the weights so that the neural network can learn how to correctly map arbitrary inputs to outputs. For the rest of this tutorial we're going to work with a single training set: given inputs 0.05 and 0.10, we want the neural network to output 0.01 and 0.99. The Forward Pass To begin, lets see what the neural network currently predicts given the weights and biases above and inputs of 0.05 and 0.10. To do this we'll feed those inputs forward though the network. We figure out the total net input to each hidden layer neuron, squash the total net input using an activation function (here we use the logistic function), then repeat the process with the output layer neurons. Total net input is also referred to as just net input by some sources. Here's how we calculate the total net input for : We then squash it using the logistic function to get the output of : Carrying out the same process for we get: We repeat this process for the output layer
