John Elder Workshop
Includes a free copy of John Elder's seminal book on Predictive Analytics

When:

Wednesday, October 4 • 9:00am - 5:00pm

Intended Audience:

Interested in the true nuts and bolts.

Knowledge Level:

Familiar with the basics of predictive modeling.

Predictive analytics has proven capable of enormous returns across industries – but, with so many core methods for predictive modeling, there are some tough questions that need answering.

What you will learn:


  • The tremendous value of learning from data.
  • How to create valuable predictive models for your business.
  • Best Practices by seeing their flip side: Worst Practices.

This one-day session surveys standard and advanced methods for predictive modeling.

Dr. Elder will describe the key inner workings of leading algorithms, demonstrate their performance with business case studies, compare their merits, and show you how to pick the method and tool best suited to each predictive analytics project. Methods covered include classical regression, decision trees, neural networks, ensemble methods, uplift modeling and more.

The key to successfully leveraging these methods is to avoid “worst practices”. It's all too easy to go too far in one's analysis and “torture the data until it confesses” or otherwise doom predictive models to fail where they really matter: on new situations.

Dr. Elder will share his (often humorous) stories from real-world applications, highlighting the Top 10 common, but deadly, mistakes. Come learn how to avoid these pitfalls by laughing (or gasping) at stories of barely averted disaster.

If you'd like to become a practitioner of predictive analytics – or if you already are, and would like to hone your knowledge across methods and best practices, this workshop is for you.
