KNIME Deep Learning - Train MNIST classifier with Keras nodes
KNIME Deep Learning - Train MNIST classifier This workflow trains a simple convolutional neural network (CNN) on the MNIST dataset viaKeras.In order to run the example, please make sure you have the following KNIME extensionsinstalled:* KNIME Deep Learning - Keras Integration (Labs)* KNIME Image Processing (Community Contributions Trusted)* KNIME Image Processing - Deep Learning Extension (Community Contributions Trusted)You also need a local Python installation that includes Keras. Please refer to https://www.knime.com/deeplearning#keras for installation recommendations and furtherinformation.
