What is MLDB?
The Machine Learning Database is a specialized database that allows users to store data, explore it using SQL commands, train machine learning models, and expose these models as APIs over a RESTful interface. It's ideal for teams needing an integrated solution for both data storage and model deployment.
Key differentiator
“MLDB stands out as an open-source, self-hosted solution that integrates data storage with machine learning capabilities through RESTful APIs and SQL support.”
