Software engineering practices applied to ML

Software engineering practices applied to ML

PyData London Meetup - April 2018 (https://www.meetup.com/PyData-London-Meetup/events/248973985/)

Stefano and Pavlos are engineers at HomeAway, and they'll talk about the benefits of applying good engineering practices when building ML-powered systems. The agenda will include:
- Feature engineering: does it have the same behaviour in training and prediction phases?
- CI/CD: are you checking for performance regressions in an automated fashion?
- Monitoring of your ML pipeline: are you sure your ML model works in production?
