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
Arguments | Description |
---|---|
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. |
… | Unused, present only for backwards compatability |
Note
It is recommended to leave the parameters of this optimizer at their default values.
