Gradient descent

Concept and definition

Gradient descent

What is Gradient descent?

Gradient descent is an optimisation algorithm used in machine learning and deep learning to adjust the parameters of a model to minimise the cost or loss function.

The goal of gradient descent is to find the values of the model parameters that minimise the cost function, i.e. those that produce the most accurate predictions. To do this, the algorithm uses the information provided by the gradient of the cost function at each iteration of the training process.

At each iteration, the gradient descent adjusts the values of the model parameters in the opposite direction to the gradient of the cost function, in order to decrease the prediction error. The learning rate is a hyperparameter of the algorithm that determines the step size at each iteration, and can be adjusted to obtain a trade-off between convergence speed and accuracy of the result.

Gradient descent is used in various machine learning and deep learning algorithms, such as linear regression, logistic regression, neural networks, among others.
