a solution created at LinkedIn to train these kinds of [ranking] models efficiently.

This divide-and-conquer approach allows for efficient training of large personalization models with commodity hardware. An improvement from its predecessor, Photon-ML, GDMix expands supports deep learning models. It can be applied to a variety of search and recommendation tasks
