The following snippet shows the usage of AdaDelta with Keras:
from keras.optimizers import Adadelta...adadelta = Adadelta(lr=0.0001, rho=0.9, epsilon=1e-6, decay=1e-2)model.compile(optimizer=adadelta, loss='categorical_crossentropy', metrics=['accuracy'])
The forgetting factor, μ, is represented by the parameter rho.
