Sample Model Building
Course DescriptionWe are now ready to build our first model in RStudio.
What You'll Learn
> Correcting column names derived from tokenization to ensure smooth model training.
> Using caret to set up stratified cross validation.
> Using the doSNOW package to accelerate caret machine learning training by using multiple CPUs in parallel.
> Using caret to train single decision trees on text features and tune the trained model for optimal accuracy.
> Evaluating the results of the cross validation process.
