As discussed, RNNs and LSTMs are highly useful for time series forecasting as the state vector and cell state allow the model to maintain context across a series. In particular, these features of sequence models allow you to carry information across a larger time window than simple deep neural networks. We also reviewed how we can use Lambda. Time series forecasting is the task of fitting a model to historical, time -stamped data in order to predict future values.
