optimizer_adagrad: Adagrad optimizer.

Description

Adagrad optimizer as described in Adaptive Subgradient Methods for Online Learning and Stochastic Optimization.

Usage

optimizer_adagrad(
  learning_rate = 0.01,
  epsilon = NULL,
  decay = 0,
  clipnorm = NULL,
  clipvalue = NULL,
  ...
)

Arguments

learning_rate

float >= 0. Learning rate.

epsilon

float >= 0. Fuzz factor. If NULL, defaults to k_epsilon().

decay

float >= 0. Learning rate decay over each update.

clipnorm

Gradients will be clipped when their L2 norm exceeds this value.

clipvalue

Gradients will be clipped when their absolute value exceeds this value.
