   Golovin Google Research • Used on many applications ◦ A/B Testing ◦ Machine Learning ◦ Physical Design ◦ Robotics • Vizier ◦ Easy to use ◦ Reliable ◦ Scalable ◦ Flexible ◦ State of the art • They tried Vizier to bake chocolate chip cookies GDP Labs Confidential

8. TFX : TensorFlow Extended - A Production Scale ML Platform

   Heng Tze Cheng Google Research • Productionizing ML pipeline is hard • End to end ( from data to serving ) • Design principles : ◦ One ML platform for many products ◦ Continuous training and serving ◦ Human in the loop ◦ Reliable and scalable • Steps : ◦ Data analysis ◦ Data validation ◦ Data transformation ◦ Trainer ◦ Model validation & evaluation ◦ Serving • Documentation -> passive way • Education -> active way ( teach, talk ) • Automation -> key principles GDP Labs Confidential

9. Designing AI at Scale to Power Everyday Life Rajesh Parekh

   Facebook • Data drives all product at Facebook • FB Learner Flow ◦ Help non ML people to use ML ◦ 70% users are non AI-experts ◦ 25% engineers are active users • Applied Machine Learning at Facebook ◦ Computer Vision ◦ Deep Text ◦ Speech and Video ◦ AI Powered Camera • What’s next ◦ Multi modal learning ◦ Transfer learning ◦ Multi lingual modeling ◦ Weakly supervised / unsupervised learning GDP Labs Confidential

10. Industrial Machine Learning Josh Bloom General Electric • Data produced

    by machines will overcome data produced by people • Industrial Machine Learning ◦ Preventive Maintenance ◦ Anomaly / Failure detection ◦ Etc • Industrial level is more dangerous than social level • Optimization metric ◦ Higher accuracy != higher value ◦ Drive towards higher precision/low FPR • Models ◦ Physical model ◦ Data driven model • Interpretability and accuracy trade off • Small improvement helps a lot • Hard to convince everyone to transition GDP Labs Confidential
