Join us for a deep dive into how ML is applied to two different public and business issues with Dataiku and WeWork!

Talk #1: Rent, Rain, and Regulations--What Predicts Crime in Portland, Oregon?

Crime poses a particularly interesting data challenge — it is both geospatial and temporal, and may be affected by many different types of variables — weather, city infrastructure, population demographics, public events, and government policy.
Jed delved into the last 6 years of crime in Portland, Oregon, pulling data from a variety of public data sets, including police reports, the US census, Foursquare, newspapers, and the weather. He will talk about how to merge, visualize, and model this type of complex data, using PostGIS, spatial mapping, time-series analyses, and machine learning, and ask what most predicts crime — and what we can do to prevent it in the future.

Jed leads the Dataiku's Data Science team in North America. He works with a wide variety of Fortune 50 clients and specializes in helping large companies spin up and organize Data Science teams. Before coming to Dataiku he worked on event detection, recommendation systems, and survival analysis in the fields of breaking news and child welfare.

Tak #2: Powered by Machine Learning: Recommendation Systems at WeWork

Team Rex at WeWork deploys intelligent applications to help our members create their life's work. One of our first products is a personalized newsfeed designed to surface the most relevant user-generated content for each member. This application is powered by a suite of recommendation models embedded within a novel multi-armed bandit-based ML platform. This framework allows for faster experimentation and more granular optimizations compared to a standard A/B testing framework.

Karry Lu is a data scientist at WeWork with interests in recommendation systems, NLP and Bayesian inference. Prior lives include relapsed statistician, community organizer and failed writer.
Alex Choi is a software engineer at WeWork, as well as a thought-leader, truth-seeker, and patriot.
