Data Preparation for Predictive Analytics

Duration: One Day Course or Two Day Workshop

Prerequisite: None

This one-day session will expose analytic practitioners, data scientists, and those looking to get started in predictive analytics to the critical importance of selecting, transforming, and properly preparing data ahead of model-building.  The instructor will present the characteristics of varying data types, how to address data quality issues, and understanding data representations that are fitting to various project types.

Participants will learn that data outliers are often not errors in the data, but sometimes the data points of most interest.  Live demonstrations will reinforce why problem context is required to understand how to deal with outliers and why undertreating extreme values can introduce model bias.  This session will cover a wide range of data preparation exercises ranging from data sandbox construction to the creation of training, test, and validation data sets for model development.

  • Prepare a data sandbox for predictive analytics
  • Detect and treat missing data and data quality issues
