Adadelta is an extension of Adagrad, which like RMSProp is trying to fix the former shortcomings. It does so by avoiding to aggregate all the past gradient since the beginning of the training regiment. Instead it uses a running average which will forget past data points in favour of newer ones. One great thing about this method is that you do not need to set a starting learning rate because it gets cancelled out in the formula process!
