This advanced machine learning masterclass will explore the many unique applications and extensions of the randomForest package, many of which are implemented in R. Access to the methods in random forest allows the user to easily solve problems not susceptible to other methods, including deep learning.
Topics will include:
- A brief overview of the random forest algorithm.
- Out-of-sample estimates on training data, and applications in fraud, risk and outlier detection—random forest can make confident predictions on training data, unlike most other methods.
- Single-model quantile regression—estimating a full distribution, not just the mean. Vital for risk-based estimation.
- The proximity matrix—a powerful visualisation, clustering and insights tool unique to random forest.
- Random forest as an unsupervised learning method—outlier detection and clustering when there are no target values—vital for fraud detection.
- ranger, a fast, flexible implementation of random forest in R.
- extraTrees (Extremely Randomized Trees), an extension to random forest that often adds more accuracy.
- Dealing with small data sets and small classes.
A range of other advanced machine learning topics, including recent works and extensions of existing packages, may also be covered.
Trainees are expected to be familiar with R, the basics of machine learning and out-of-sample error estimation, and the basic workings of the random forest algorithm.

Testimonials
The Introduction to R course provided clear and logical assistance to getting up and running with R. More than that, the real value was in providing guidance on the myriad of online resources and introducing me to a network of passionate and helpful R users. Eugene is a knowledgeable and approachable teacher. I wouldn’t hesitate in recommending the course. I feel that I am now fully on the road to applying R and using data to improve efficiency across my organisation.
For someone who does not come from an IT background R is a terrifying program. Before doing the Introduction to R course I had previously done other courses in R but always found myself in over my head because they assumed a high level of program experience (even course that required no prior programming knowledge). This course is not like that at all. It starts at ground zero and teaches you everything you need to know to be able to use R confidently in your everyday workplace. It is a must attend for anyone who wants use R!
