Apache MADlib: Big Data Machine Learning in SQL
Open source, commercially friendly Apache license
For PostgreSQL and Greenplum Database
Powerful machine learning, graph, statistics and analytics for data scientists
Getting Started with Apache MADlib using Jupyter Notebooks
We have created a
library of Jupyter Notebooks
to help you get started quickly with MADlib. It
includes many commonly used algorithms by data scientists.
MADlib 2.1.0 Release
On September 8, 2023, MADlib completed its thirteenth release as an Apache Software Foundation Top Level Project.
