Level

Beginner

Prerequisite knowledge

* Basic understanding of ML. * Basic understanding of computer engineering. * (Nice-to-have) Beginner knowledge in TensorFlow.

What you'll learn

* What does a scalable production ML pipeline look like at Twitter today? * Lessons we learned while unifying Twitter's ML tech stack. * Which problems do ML solve at Twitter? * How to create platform that is flexible enough to serve a diversity of ML needs?

Description

Twitter is a 4000+ employee company with many ML use cases. Historically, there are many different ways to productionize ML at Twitter. Across the company, we had users of TensorFlow, Lua Torch, PyTorch, Scikit Learn, VW, XGBoost, and several other Twitter in-house solutions. In this session, we are going to discuss:

  • the pain points of having fragmented ML practices;
  • how the Twitter Cortex team is unifying Twitter teams around a single ML platform;
  • current status of the ML platform and who are the internal customers;
  • how the production pipeline looks like and how customers use it;
  • where is the unified ML production platform heading in the future.
