The Galaxy Machine Learning workbench is a comprehensive set of data preprocessing, machine learning, deep learning and visualisation tools, consolidated workflows for end-to-end machine learning analysis and training materials to showcase the usage of these tools. The workbench is available on the Galaxy framework{:target="_blank"}, which guarantees simple access, easy extension, flexible adaption to personal and security needs, and sophisticated machine learning analyses independent of command-line knowledge.
The workbench provides you with a Swiss Army knife of scikit-learn{:target="_blank"}, Keras{:target="_blank"} (a deep learning library based on TensorFlow{:target="_blank"}) and various other tools to transform, learn and predict and plot your data.
The workbench is currently developed by the Goecks Lab and the European Galaxy project{:target="_blank"}. The German Network for Bioinformatics Infrastructure (de.NBI){:target="_blank"}, which runs the German ELIXIR Node{:target="_blank"}, provides the necessary compute clusters with CPUs and GPU resources.
The project is a community effort, please jump in, ask questions, and contribute to the development of new tools, workflows or trainings!

Are you new to Galaxy, or returning after a long time, and looking for help to get started? Take [a guided tour]({{ page.website }}/tours/core.galaxy_ui){:target="_blank"} through Galaxy's user interface.
We are passionate about training. So we are working in close collaboration with the Galaxy Training Network (GTN){:target="_blank"} to develop training materials of data analyses based on Galaxy {% cite batut2017community %}. These materials hosted on the GTN GitHub repository are available online at https://training.galaxyproject.org{:target="_blank"}.
Want to learn more about machine learning? Take one of our guided tours or check out the following hands-on tutorials, developed together with the GTN community.
In this section we list the most important tools that have been integrated into the Machine Learning workbench. There are many more tools available so please have a more detailed look at the tool panel. For better readability, we have divided them into categories.
