Machine Learning at Pinterest

Machine Learning is key to Pinterest. Millions of millions of Pinners interact with the site every day by browsing, searching, saving, and clicking through to external sites. Machine learning is essential because it helps people discover the content things they love and inspire them to go do them. Pinterest’s machine learning researchers and engineers develop machine learning algorithms that rank Pins and search results, filter abusive and misleading content, place ads, and design optimal educational experiences for new users. We develop new computer vision models that can “see” the content of the Pin and our machine learning systems rank nearly 300 billion pins every day.
