What it does
Aim is a self-hosted tool that records your machine learning training runs and any related data, so you can keep track of your experiments.
It provides a visual interface to explore and compare many runs side by side, plus a way to query the recorded data from code.
Its makers say it is built to handle very large numbers of training runs.
Who it's for
Machine learning practitioners who want to track and compare their experiments.
