Overview of this book

KNIME Analytics Platform is an open source software used to create and design data science workflows. This book is a comprehensive guide to the KNIME GUI and KNIME deep learning integration, helping you build neural network models without writing any code. It’ll guide you in building simple and complex neural networks through practical and creative solutions for solving real-world data problems. Starting with an introduction to KNIME Analytics Platform, you’ll get an overview of simple feed-forward networks for solving simple classification problems on relatively small datasets. You’ll then move on to build, train, test, and deploy more complex networks, such as autoencoders, recurrent neural networks (RNNs), long short-term memory (LSTM), and convolutional neural networks (CNNs). In each chapter, depending on the network and use case, you’ll learn how to prepare data, encode incoming data, and apply best practices. By the end of this book, you’ll have learned how to design a variety of different neural architectures and will be able to train, test, and deploy the final network.

Accessing Data

Before starting with examples of how to access and import data into a KNIME workflow, let's create the workflow:

  1. Click on the File item in the top menu or right-click on a folder, such as LOCAL, for example, in KNIME Explorer.
  2. Then, select the New KNIME Workflow option.
  3. Give it a name – for example, Ch2_Workflow_Examples – and a destination.

    An empty canvas will open in the central part of the KNIME workbench: the workflow editor.

For this chapter, we will use toy data already available at installation. A set of workflows is installed together with the core KNIME Analytics Platform. You can find them in the Example Workflows folder (Figure 2.1) in the KNIME Explorer panel. Its TheData sub-folder contains some free toy datasets:

We will mainly use the datasets in the Misc sub-folder.
