Download KNIME analytics platform, one of the most popular free/open-source software tools from knime. org. Identify the deep learning examples (where Keras is used to build some exemplary prediction/classification models) in its example folder. Study the models in detail. Understand what it does and how exactly it does it. Then, using a different but similar data set, build and test your own deep learning prediction model. Report your findings and experiences in a written document.
