Overview of this book

This book will take you on a practical journey, teaching you how to implement solutions for many use cases involving time series analysis techniques. This learning journey is organized in a crescendo of difficulty, starting from the easiest yet effective techniques applied to weather forecasting, then introducing ARIMA and its variations, moving on to machine learning for audio signal classification, training deep learning architectures to predict glucose levels and electrical energy demand, and ending with an approach to anomaly detection in IoT. There’s no time series analysis book without a solution for stock price predictions and you’ll find this use case at the end of the book, together with a few more demand prediction use cases that rely on the integration of KNIME Analytics Platform and other external tools. By the end of this time series book, you’ll have learned about popular time series analysis techniques and algorithms, KNIME Analytics Platform, its time series extension, and how to apply both to common use cases.

Chapter 10: Predicting Energy Demand with an LSTM Model

In this chapter, we’ll continue our brief foray into deep learning topics and employ a special neural unit called a long short-term memory (LSTM) unit. This will leverage the versatility of the recursive neural network (RNN) and expand on its ability to pull information from past events.

The goal of this chapter is to introduce a theoretical understanding of the LSTM unit, as well as build a forecasting model for Electrical Energy Consumption. Understanding the inner workings of the LSTM unit will be important when deciding if this model type is more appropriate than the standard feedforward network from the previous chapter.

In this chapter, we will cover the following topics:

  • Introducing recurrent neural networks and LSTMs
  • Encoding and tensors
  • Training an LSTM-based neural network

By the end of the chapter, you will understand the inner workings of the LSTM unit and understand when to use...
