The LSTM-M approach for traffic flow prediction is a promising method because it has both a long- and short-term mechanisms for simulating missing data in the input variables and the residuals between the initial predictions and the ground-truth values, which are caused by the complex patterns in the missing data, are explicitly learned. Demonstrates how to use stateful RNNs to model long sequences efficiently. Step 2 (building the model) is an ease with the R keras package, and it in fact took only 9 lines of code to build and LSTM with one input layer, 2 hidden LSTM layers with 128 units each and a softmax output layer, making it four layers in total. 344049 Conclusion In general the best results are a combination of using wavelet transformation, Stacked Auto Encoders, Tweets sentiment and GRU/LSTM, with I-STM generating slightly better results than GRU. Pytorch Free Gpu Memory. LSTM networks can be stacked in Keras in the same way that other layer types can be stacked.
