Main themes

An important task in data mining is the discovery of patterns in data. Patterns are recurring structures in data; they can provide interpretable explanations for observations in data, can help to gain a better understanding in the structure of data, can be used to build better models, and can be used to solve other computational tasks (such as the construction of database indexes or data compression). Patterns can be found in many different forms of data, including data from supermarkets, insurance companies, scientific experiments, social networks, software projects, and so on.

This course will provide an in-depth introduction to pattern mining. After an introduction to the basics of pattern mining, it will provide an in-depth discussion of a number of advanced pattern mining techniques.

Topics that will be discussed are:

  • Categories of pattern mining tasks, including pattern and pattern set mining, supervised and unsupervised pattern mining, dataset types,and pattern scoring functions;
  • Algorithms for solving different pattern mining tasks;
  • Data structures for making pattern mining more efficient;
  • The implementation of pattern mining algorithms;
  • Mathematical foundations for the different categories of pattern mining tasks;
  • Complexity classes relevant to pattern mining;
  • Applications of pattern mining, with a special focus on the application of pattern mining techniques in software engineering.
