The Cook County Assessor’s Office (CCAO) is responsible for determining the assessed value of over 1.8 million properties. Last year, the CCAO’s Data Department presented V2 of its residential valuation model, which was used to reassess the City of Chicago. The model outperformed previous CCAO valuation models, but still had some rough edges. This year, the Data Department created V3 of its residential valuation model. The new model includes a vastly expanded set of input features, significantly improved methods, stricter accounting for different modeling experiments, and more. The result is the CCAO's fastest, most accurate valuation model to date.

There will be no presentation this week. Instead, we're going to have an Open Hack. Join our 7pm open Zoom call for introductions, socializing, announcements and breakout groups.
