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.

Classifying Images with CNNs

In this section, we will see how to build and train from scratch a CNN for image classification.

The goal is to classify handwritten digits between 0 and 9 with the data from the MNIST database, a large database of handwritten digits commonly used for training various image-processing applications. The MNIST database contains 60,000 training images and 10,000 testing images of handwritten digits and can be downloaded from this website: http://yann.lecun.com/exdb/mnist/.

To read and preprocess images, KNIME Analytics Platform offers a set of dedicated nodes and components, available after installing the KNIME Image Processing Extension.

Tip

The KNIME Image Processing Extension (https://www.knime.com/community/image-processing) allows you to read in more than 140 different format types of images (thanks to the Bio-Formats Application Processing Interface (API)). In addition, it can be used to apply well-known image-processing techniques such as...
