optimizer_adadelta: Adadelta optimizer.

In dfalbel/keras: R Interface to 'Keras'

Description

Adadelta optimizer as described in ADADELTA: An Adaptive Learning Rate Method.

Usage

optimizer_adadelta(
  lr = 1,
  rho = 0.95,
  epsilon = NULL,
  decay = 0,
  clipnorm = NULL,
  clipvalue = NULL
)

Arguments

lr	float >= 0. Learning rate.
rho	float >= 0. Decay factor.
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.

Note

It is recommended to leave the parameters of this optimizer at their default values.
