Backpropagation from Scratch in Python

A python notebook that implements backpropagation from scratch and achieves 85% accuracy on MNIST with no regularization or data preprocessing. The neural network being used has two hidden layers and uses sigmoid activations on all layers except the last, which applies a softmax activation.

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.


How backpropagation works, and how you can use Python to build a neural network Artificial

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.

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?

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.

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.

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.

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.
