Model Registry

Term from Machine Learning industry explained for recruiters

A Model Registry is like a smart storage system for artificial intelligence and machine learning projects. Think of it as a library that keeps track of all the AI models a company creates, along with important information about how well they work and how they were made. Just like how a company needs a system to manage employee records, data scientists need a way to organize and track their AI models. This helps teams work together better, ensures they can easily find and reuse successful models, and helps maintain quality standards. Popular tools for this include MLflow, Weights & Biases, and Neptune.ai.
