Machine learning, a subset of artificial intelligence, has revolutionized the way we solve complex problems. At the heart of many machine learning algorithms lies the concept of gradients. Gradients are essential mathematical tools that guide the learning process by telling us how to update the parameters of a model to minimize errors or maximize performance. In this article, we will delve into the essence of gradients in machine learning, explaining their significance, how they work, and their role in various algorithms. Understanding Gradients In the context of machine learning, a gradient represents the direction and magnitude of the steepest increase or decrease in a function. It's a vector that points in the direction of the maximum rate of increase of the function. Gradients are pivotal in optimizing machine learning models because they help us find the minimum or maximum of a loss or objective function, which is a fundamental concept taught in a machine learning course .
