optimizer_adadelta {keras} | R Documentation |
Adadelta optimizer as described in ADADELTA: An Adaptive Learning Rate Method.
optimizer_adadelta(lr = 1, rho = 0.95, epsilon = NULL, decay = 0, clipnorm = NULL, clipvalue = NULL)
lr |
float >= 0. Learning rate. |
rho |
float >= 0. Decay factor. |
epsilon |
float >= 0. Fuzz factor. If |
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. |
It is recommended to leave the parameters of this optimizer at their default values.
