June 06, 2017 | 14 Minute Read D eep learning is the study of artificial neural networks and related machine learning algorithms that contain more than one hidden layer. LSTM networks have a repeating module that has 4 different neural network layers interacting to deal with the long term dependency problem. The inputs will be time series of past performance data of the application, CPU usage data of the server where application is hosted, the Memory usage data, network bandwidth usage etc. LSTM is basically kind of a neural network node in a recurrent neural network. This might not be the behavior we want. Since we have extensive experience with Python, we used a well-documented package that has been advancing by leaps and bounds: TensorFlow. In case anyone's interested, I've solved the problem now - basically, predict seems to output a sequence, which is as long as the input sequence. They are extracted from open source Python projects. The idea of this post is to provide a brief and clear understanding of the stateful mode, introduced for LSTM models in Keras. In a previous tutorial series I went over some of the theory behind Recurrent Neural Networks (RNNs) and the implementation of a simple RNN from scratch.

First, notice that a LSTM layer is just another way to compute a hidden state. This is different from, say, the MPEG-2 Audio Layer III (MP3) compression algorithm, which only holds assumptions about "sound" in general, but not about specific types of sounds. LSTM networks have a repeating module that has 4 different neural network layers interacting to deal with the long term dependency problem. A Keras sequential model is basically used to sequentially add layers and deepen our network. In fact, it seems like almost every paper involving LSTMs uses a slightly different version.

Since we have extensive experience with Python, we used a well-documented package that has been advancing by leaps and bounds: TensorFlow. I then replaced the LSTM layer with a Dense layer just to see the effect (I did remove the Return=False argument). We will have to use TimeDistributed to pass the output of RNN at each time step to a fully connected layer. Specifying the input shape. Learned from a friend: if you have access to a GPU, you'll want to use CuDNNLSTM rather than LSTM layers, to save on training times!
