Jack Dorsey Shed Some Light on How Twitter Uses Machine Learning, Deep Learning on Its Timeline

Twitter CEO Jack Dorsey discussed how the social network is using machine learning and deep learning to populate its timeline during the company's annual shareholders' meeting conference call Monday. Dorsey said showing Twitter users what's happening and delivering them the news of the day is the social network's "singular job," and he discussed changes to the timeline over the past year-and-a-half: This is where people spend almost all of their time on Twitter. This is where they get all of their news, see everything that's going on, see what people think about what's going on. And for the longest time, it just hasn't been personalized. It's been completely ordered by recency.
