A roadmap connecting many of the most important concepts in machine learning, how to learn them and what tools to use to perform them.
See the full interactive version.
Watch a feature-length film video walkthrough (yes, really, it's longer than most movies).
Many of the materials in this roadmap were inspired by Daniel Formoso's machine learning mindmaps,so if you enjoyed this one, go and check out his. He also has a mindmap specifically for deep learning too.
