Training a recommender model of 100 trillions parameters on Google Cloud

#artificialintelligence 

A recommender system is an important component of Internet services today: billion dollar revenue businesses are directly driven by recommendation services at big tech companies. The current landscape of production recommender systems is dominated by deep learning based approaches, where an embedding layer is first adopted to map extremely large-scale ID type features to fixed-length embedding vectors; then the embeddings are leveraged by complicated neural network architectures to generate recommendations. The continuing advancement of recommender models is often driven by increasing model sizes--several models have been previously released with billion parameters up to even trillion very recently. Every jump in the model capacity has brought in significant improvement on quality. The era of 100 trillion parameters is just around the corner.
