What you'll learn

  • Learn how Pinterest maintains a healthy ecosystem around machine-learning products


As Pinterest undergoes explosive growth in its user base, the content corpus that users contribute to is also rapidly expanding. The content and the machine-learning algorithms exist in a feedback cycle where content signals power the algorithms and algorithms influence the content that populates the ecosystem. A major algorithm change can significantly impact how content is exposed. Without proactive monitoring in place, the makeup of the exposed content can drift over time, in a direction that may not be the most beneficial to users in the long term.

Grace Huang offers a glimpse into the unique challenges of maintaining a healthy ecosystem around machine-learning products at Pinterest. Grace explores the suite of tools Pinterest built to make sense of machine-learning experiment results and the panel of metrics it developed to help gauge the health of the content ecosystem and shares the story of a cross-functional effort to ensure that quality content can thrive in the the ecosystem and make its way to pinners who will find it relevant and engaging.
