Backpropagation, often referred to as “backward propagation of errors,” is the cornerstone of training deep neural networks. It is a supervised learning algorithm that optimizes the weights and biases of a neural network to minimize the error between predicted and actual outputs.

This blog post provides a highly technical yet understandable exploration of backpropagation, detailing its mechanics, mathematical foundations, and practical applications, making it accessible to those with a basic understanding of calculus and machine learning. Backpropagation is a gradient-based optimization algorithm used to train artificial neural networks, particularly feed-forward networks. It iteratively adjusts the network’s parameters to minimize a loss function, which quantifies the discrepancy between the network’s predictions and the true labels. The algorithm’s efficiency stems from its use of the chain rule to compute gradients layer by layer, enabling scalable training of deep architectures. Backpropagation’s roots trace back to Seppo Linnainmaa’s 1970 work on reverse-mode automatic differentiation, with significant contributions by Paul Werbos (1982) and the formalization by David E. Rumelhart, Geoffrey Hinton, and Ronald J.

Williams in their 1986 paper, “Learning representations by back-propagating errors.” Its adoption in the 1980s, coupled with GPU advancements in the 2010s, revolutionized deep learning, enabling applications in computer vision, natural language processing, and...

Have you ever wondered how neural networks actually learn?

The answer is true grit. Fail 1,000 times get up 1,001 times. As it turns out they’re not that different from people. They make a mistake, they try to figure out how they went wrong, get back up and try it again until it works. The algorithm that handles figuring out where things went wrong and how to do better is called backpropagation. Today we’re going to demystify it using a simple Python implementation based on the micrograd engine.

Backpropagation is the algorithm that makes neural networks learn from their mistakes. Think about it like a student studying for an upcomming test taking a practice test. First they take the exam and recieve a lower score than they were hoping for. The next step is to look at the answer key and figure which questions have wrong answers. Out of those questions they got wrong they might ask themselves which areas were worth the lost them the most points, then develop a study plan to improve in those areas take the test... In technical terms, backpropagation looks at the output results from the model compares them to the expected results, measures the losses and calculates gradients to figure out what went wrong, which part of model...

Before diving into the code, let’s understand the chain rule — the mathematical underpinning of backpropogation and hopefully by the end they will start to sound very similar. Imagine you’re a chef creating a multi-layered sandwich. Each layer represents a different part of the sandwich-making process, and your goal is to figure out how the flavor of the final sandwich changes when you tweak the amount of one ingredient. this repo contain the solutions of the code exercises from the "Understanding Deep Learning " by Simon J.D.
