a solution created at LinkedIn to train these kinds of [ranking] models efficiently. It breaks down a large model into a global model (a.k.a. “fixed effect”) and a large number of small models (a.k.a. “random effects”), then solves them individually. 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–a-deep-ranking-personalization-framework
