How to build your own Neural Network from scratch in Python

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.

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.

We will start from Linear Regression and use the same concept to build a 2-Layer Neural Network.Then we will code a N-Layer Neural Network using python from scratch.As prerequisite, you need to have basic understanding of Linear/Logistic Regression with Gradient Descent. Let's see how we can slowly move towards building our first neural network.

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.

Sep 23, 2021 In the last story we derived all the necessary backpropagation equations from the ground up. We also introduced the used notation and got a grasp on how the algorithm works. In this story we'll focus on implementing the algorithm in python. Let's start by providing some structure for our neural network


Implementing Backpropagation From Scratch on Python 3+ by Essam Wisam Towards Data Science

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.

Backpropagation from scratch with Python PyImageSearch

Backpropagation is arguably the most important algorithm in neural network history — without (efficient) backpropagation, it would be impossible to train deep learning networks to the depths that we see today. Backpropagation can be considered the cornerstone of modern neural networks and deep learning.
