Time Series Prediction with LSTM Recurrent Neural Networks in Python with Keras

Last Updated on August 28, 2020 Time series prediction problems are a difficult type of predictive modeling problem. Unlike regression predictive modeling, time series also adds the complexity of a sequence dependence among the input variables. A powerful type of neural network designed to handle sequence dependence is called recurrent neural networks. The Long Short-Term Memory network or LSTM network is a type of recurrent neural network used in deep learning because very large architectures can be successfully trained. In […]

Instability of Online Learning for Stateful LSTM for Time Series Forecasting

Last Updated on August 28, 2020 Some neural network configurations can result in an unstable model. This can make them hard to characterize and compare to other model configurations on the same problem using descriptive statistics. One good example of a seemingly unstable model is the use of online learning (a batch size of 1) for a stateful Long Short-Term Memory (LSTM) model. In this tutorial, you will discover how to explore the results of a stateful LSTM fit using […]
