Adding Predictive Analytics to Existing BI Team - Abstract

Many organizations have a Business Intelligence group or several that provide reports and data to leadership. A majority of these activities revolve around descriptive analytics trying to answer the question “What has Happened?”. Our presentation focuses on the challenges and lessons learned of adding improved analytics and predictive analytics skills to an existing BI team without breaking the budget. We discuss our grassroots approach and lessons learned through the early stages of our journey to provide greater insights to business decision makers.

Random Forest and Cart Decision Trees using R - Abstract

Data Science using open source tools, building and evaluating models, using decision trees and ensemble methods such as random forest. This talk will cover the importance of data preparation and discuss a few algorithm implementations. Data science problems are not solved by just throwing together complex algorithms, advanced machinery, time, and data (and we already know the answer to that is 42). It takes creativity to prepare the analytic data sets, and the best algorithm to use depends on the data and the business question.
