Ada-Delta method doesn't converge when used in Denoising AutoEncoder with MSE loss & ReLU activation?
I just implemented AdaDelta (http://arxiv.org/abs/1212.5701) for my own Deep Neural Network Library.
The paper kind of says that SGD with AdaDelta is not sensitive to hyperparameters, and that it ...
