Adagrad Optimization Algorithm

Algorithm

Adagrad, short for Adaptive Gradient Algorithm, represents a stochastic gradient descent (SGD) optimization technique designed to address the challenges of varying learning rates across different parameters within a model. It adapts the learning rate for each parameter individually, diminishing the learning rate for frequently occurring parameters and increasing it for infrequent ones. This adaptive behavior is achieved by maintaining a per-parameter running average of the squared gradients, effectively normalizing the learning rate based on the historical gradient magnitudes. Consequently, Adagrad proves particularly useful in scenarios where features exhibit vastly different frequencies, a common characteristic in natural language processing and, increasingly, in the analysis of high-frequency cryptocurrency trading data.
