Every spring semester

The course begins with an overview of basic data wrangling and visualisation. With a focus on the student's ability to identify and illustrate important features of the data.

Then important methods in statistical learning are introduced. Emphasis is given to dimension reduction, supervised and unsupervised learning. Issues arising from fitting multiple models (i.e. multiple testing) as well as the methods relationship to regression are discussed. Computer based labs and projects form an important part of the learning activities. The course concludes with a project where the students will select suitable methods to analyze a given data material.

* Basic methods for data handling and common visualisation methods for data
* Methods for data reduction such as Principal Component Analysis (PCA) and their use for imputation of missing data.
* Methods for unsupervised and supervised learning/classification such as: Support Vector Machines (SVM), clustering (K-means), hierarchical clustering, simpler regression methods, and methods for decision trees (bagging, boosting, and random forests).
* Multiple testing and common solutions such as Benjamini-Hochberg and Bonferroni.
