Webthat even a purely supervised but greedy layer-wise proce-dure would give better results. So here instead of focus-ing on what unsupervised pre-training or semi-supervised criteria bring to deep architectures, we focus on analyzing what may be going wrong with good old (but deep) multi-layer neural networks. WebInspired by the success of greedy layer-wise training in fully connected networks and the LSTM autoencoder method for unsupervised learning, in this paper, we propose to im-prove the performance of multi-layer LSTMs by greedy layer-wise pretraining. This is one of the ﬁrst attempts to use greedy layer-wise training for LSTM initialization. 3. file mind mapping
