# Machine Learning Knowledge Graph



[![Machine Learning Knowledge Graph](cover.png)](https://leandromineti.github.io/ml-knowledge-graph/)



Machine learning emerges from the intersection of many fields of study. Important

concepts in these areas are related in many ways. The aim with this graph is to 

highlight the connections between those concepts and, hopefully, help us navigate

this complex idea space. Currently, [the graph has 206 nodes and 278 edges](https://leandromineti.github.io/ml-knowledge-graph/).



The concepts were classified in 5 categories:



- Mathematics

- Statistics

- Machine Learning

- Optimization

- Artificial Intelligence



A category called "Other" was added to list important related research areas. 

Some concepts lie on the intersection of fields and are hard to classify. An 

effort was made to put them where they are used more frequently. The topics 

covered on the graph are listed below.

## FAQ



- **Why make a distinction between Machine Learning and Artificial Intelligence?**



I followed the approach explored by Russel and Norvig [1]. In that sense, Artificial

Intelligence is a broader field that encompasses Machine Learning.
