Machine Learning at Twitter: Twitter Meets Tensorflow

AI & Data, Novice
8/19/2018 | 1:20 PM-1:50 PM | Robertson


Twitter is a company with massive amounts of data. Thus, it is no wonder that the company applies machine learning in various ways: from Timeline Ranking to Ads. This talk will be focused on our most recent ML platform, which is built on top of (Python) Tensorflow. We will give you an idea of how we are doing ML at Twitter’s scale and what our platform provides on top of Tensorflow.


Machine Learning has allowed Twitter to drive engagement, promote healthier conversations, and deliver catered advertisements. Over the past year, we have been working on a new chapter of ML at Twitter by migrating our machine learning platform from Lua Torch to (Python) Tensorflow. This talk will be mainly focusing on the Machine Learning framework we have been developing on top of Tensorflow. More especially, how it allows for teams inside the company to run their models in production at Twitter’s scale. We plan to discuss: - Our migration from Lua Torch to Tensorflow - The additions of our framework on top of Tensorflow - How we productionalize our model
