 Codeless Deep Learning with KNIME

This is the code repository for Codeless Deep Learning with KNIME, published by Packt.

Build, train, and deploy various deep neural network architectures using KNIME Analytics Platform

What is this book about?

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.

This book covers the following exciting features:

  • Use various common nodes to transform your data into the right structure suitable for training a neural network
  • Understand neural network techniques such as loss functions, backpropagation, and hyperparameters
  • Prepare and encode data appropriately to feed it into the network
  • Build and train a classic feedforward network
  • Develop and optimize an autoencoder network for outlier detection

codeless-deep-learning-with-knime's Issues

Some Knime workflow examples using the "Keras Network Learner" node do not work

This is a very informative book. However, some of the example workflows that involve the "Keras Network Learner" do not work, e.g. the training workflow in Chapter 6, or Generate Fairy tales in Chapter 7. At least in Knime 4.4 under macos 11.5.2 I get the following errors:

WARN Keras Network Learner 0:85 The number of rows of the input training data table (41291) is not a multiple of the selected training batch size (256). Thus, the last batch of each epoch will continue at the beginning of the training data table after reaching its end. You can avoid that by adjusting the number of rows of the table or the batch size if desired.
WARN Keras Network Learner 0:85 /Users/herbert/Software/A/anaconda3/envs/py3_knime_dl/lib/python3.6/site-packages/keras/engine/saving.py:292: UserWarning: No training configuration found in save file: the model was not compiled. Compile it manually.
ERROR Keras Network Learner 0:85 java.lang.Exception: Failed to receive message from Python or forward received message.
ERROR Keras Network Learner 0:85 Execute failed: An error occured during training of the Keras deep learning network. See log for details.

This is a pity since ffor a beginner it is almost impossible to find out what causes the errors, and makes the book a lot less useful. In the end, a python script might be better to use?

Cheers,
Herbert
