Tools for Discovering Patterns in Data

Elder Research is presenting a 2-day course, “Tools for Discovering Patterns in Data: Extracting Value from Tables, Text, and Links,” on September 22 - 23 in Charlottesville, Virginia. Drawing on more than 20 years of experience, Dr. John Elder will explain techniques employed by experts to solve challenging problems.This course describes powerful analytic methods for classification and estimation drawn from Statistics and Data Mining. Dr. Elder will explain leading algorithms, compare their merits, and demonstrate their effectiveness on practical applications .Also review classical statistical techniques, and outline how they are modified and combined into modern methods. The course emphasizes practical advice and the essential techniques of Resampling, Visualization, and Ensembles. Actual scientific and business examples illustrate techniques employed by expert analysts. Key aspects of mining text and links will also be outlined, and major strengths of leading commercial software tools for Data Mining will be compared.
