FTRL is an abbreviation for “Follow-The-Regularized-Leader” and is an optimization algorithm specifically designed for online learning scenarios. It was developed to work efficiently with large-scale and sparse data. This algorithm, proposed by Google, is widely used in ad prediction, recommendation systems, and real-time learning systems.

FTRL Optimization Algorithm

Core Approach

Unlike classical gradient descent methods, FTRL updates parameters based on a combination of accumulated gradients from previous steps and regularization terms. In particular, it incorporates


FTRL enables online and sparse learning by accounting for past gradients and regularization terms.
