Codeless Deep Learning with KNIME

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.

Chapter 2: Data Access and Preprocessing with KNIME Analytics Platform

Before deep-diving into neural networks and deep learning architectures, it might be a good idea to get familiar with KNIME Analytics Platform and its most important functions.

In this chapter, we will cover a few basic operations within KNIME Analytics Platform. Since every project needs data, we will first go through the basics of how to access data: from files or databases. In KNIME Analytics Platform, you can also access data from REST services, cloud repositories, specific industry formats, and more. We will leave the exploration of these other options to you.

Data comes in a number of shapes and types. In the Data Types and Conversions section, we will briefly investigate the tabular nature of the KNIME data representation, the basic types of data in a data table, and how to convert from one type to another.

At this point, after we have imported the data into a KNIME workflow, we will show some basic...
