SF Data Mining January 26, 2015 Deploying predictive models Nick  Elprin   Domino  Data  Lab   dominodatalab.com 

Who am I? SF Data Mining January 26, 2015 • Founder of Domino Data Lab, a software platform for enterprise data science
 
 
 • Previously built analytical software at a big hedge fund
 
 
 • BA, MS in computer science 

Motivation SF Data Mining January 26, 2015 Build predictive models Build production software systems Different languages good for different tasks 

Motivation SF Data Mining January 26, 2015 Organizational design friction Model improvements Data Scientists Software Engineering Delayed because of: • Integration / porting of logic • Out-of-phase release cycles • Mismatched priorities 

Solution SF Data Mining January 26, 2015 Publish Consume Data scientists create predictive models and publish  them  to  Domino. Domino provides a secure, low- latency infrastructure for hosting predictive models as  web  services Developers can invoke models from general purpose languages by making simple  HTTP  calls • Failover • Security • Logging • Seamless updates • etc 

Demo SF Data Mining January 26, 2015 

Production concerns SF Data Mining January 26, 2015 •Very low latency •Zero-downtime upgrades •High availability •Reproducibility •Logging •Security 

Best practices SF Data Mining January 26, 2015 •Separate training, initialization, and prediction •Make your prediction functions thread-safe •Don’t mutate any shared state •Leverage persistence/serialization tools (e.g., pickle) 

Use cases SF Data Mining January 26, 2015 •Lease / loan approval •Recommendation systems •Music, books, products, cars, etc •Insurance •Quoting premiums; claims estimates
