Who is this presentation for?

  • Data scientists and data engineers

Prerequisite knowledge

  • A basic working knowledge of Spark and Elasticsearch
  • Familiarity with recommender systems (useful but not required)

What you'll learn

  • Learn how to build a large-scale, end-to-end recommender system using Spark Streaming, Spark ML, and Elasticsearch

Description

There are many resources available for learning how to use Spark to build collaborative filtering models. However, there are relatively few that explain how to build a large-scale, end-to-end recommender system. Seth Hendrickson demonstrates how to create such a system using Spark Streaming and Elasticsearch for data ingestion and storage, Spark DataFrames and ML pipelines for data aggregation and model building, and Elasticsearch for model management and serving. Along the way, Seth explores techniques for scaling model serving, using Spark Streaming for real-time incremental model updates, and incorporating state-of-the-art models into this framework.
