Backpropagation From Scratch With Python Pyimagesearch www.vrogue.co
Aug 9, 2022 This article focuses on the implementation of back-propagation in Python. We have already discussed the mathematical underpinnings of back-propagation in the previous article linked below. At the end of this post, you will understand how to build neural networks from scratch. How Does Back-Propagation Work in Neural Networks?

Backpropagation is something on which experimentation can be done while playing around. Why Mini-Batches? The reason behind mini-batches is simple. It saves memory and processing time by dividing data into mini-batches and supply the algorithm a fraction of the dataset on each iteration of the training loop.

We'll work on detailed mathematical calculations of the backpropagation algorithm. Also, we'll discuss how to implement a backpropagation neural network in Python from scratch using NumPy, based on this GitHub project. The project builds a generic backpropagation neural network that can work with any architecture. Let's get started.
How to build your own Neural Network from scratch in Python
Backpropagation — the "learning" of our network. Since we have a random set of weights, we need to alter them to make our inputs equal to the corresponding outputs from our data set. This is done through a method called backpropagation. Backpropagation works by using a loss function to calculate how far the network was from the target output.

The backpropagation algorithm works in the following steps: Initialize Network: BPN randomly initializes the weights. Forward Propagate: After initialization, we will propagate into the forward direction. In this phase, we will compute the output and calculate the error from the target output.

The backpropagation algorithm is a type of supervised learning algorithm for artificial neural networks where we fine-tune the weight functions and improve the accuracy of the model. It employs the gradient descent method to reduce the cost function. It reduces the mean-squared distance between the predicted and the actual data.
Making Backpropagation, Autograd, MNIST Classifier from scratch in Python by Andrey Nikishaev
Technically, the backpropagation algorithm is a method for training the weights in a multilayer feed-forward neural network. As such, it requires a network structure to be defined of one or more layers where one layer is fully connected to the next layer. A standard network structure is one input layer, one hidden layer, and one output layer.
GitHub Neural Network Backpropagation
The back-propagation algorithm is iterative and you must supply a maximum number of iterations (50 in the demo) and a learning rate (0.050) that controls how much each weight and bias value changes in each iteration. Small learning rate values lead to slow but steady training.
