This is a follow-up to my earlier post on learning curves. A learning curve is a plot of predictive error for training and validation sets over a range of training set sizes. Here we’re using simulated data to explore some fundamental relationships between training set size, model complexity, and prediction error.

Start by simulating a dataset:

I love typography, and I love sci-fi, and I'm probably not alone in that combination of interests.

If you're new to the concept of predictive models, or just want to review the background on how data scientists learn from past data to predict the future, you may be interested in my talk from the Data Insights Summit, Introduction to Real-Time Predictive Modeling.

Last year, I wrote the New York R Conference “set the bar pretty darn high for a first time conference”. Not only was there an outstanding lineup of speakers, but the energy and enthusiasm that conference attendees brought with them, or maybe just generated on the spot, was remarkable.

That's all from us at the blog for this week. See you back here next on Monday (and if you're in the Seattle area, maybe I'll see you in person at the R User Group meeting). Have a great weekend!
