Persia: An Open, Hybrid System Scaling Deep Learning-based Recommenders up to 100 Trillion Parameters

Lian, Xiangru, Yuan, Binhang, Zhu, Xuefeng et al.

Understand

Deep learning based models have dominated the current landscape of production recommender systems.

  • Furthermore, recent years have witnessed an exponential growth of the model scale--from Google's 2016 model with 1 billion parameters to the latest Facebook's model with 12 trillion parameters.
  • Significant quality boost has come with each jump of the model capacity, which makes us believe the era of 100 trillion parameters is around the corner.
  • However, the training of such models is challenging even within industrial scale data centers.
