CS909 Data Mining

Pre-requisites

No Warwick module is required as pre-requisite. However familiarity with basic probability and statistics (for example: discrete and continuous random variables, densities and distributions, common distributions including Bernoulli, binomial, uniform and normal distribution, expectations) will be needed.

Academic Aims

  • Understanding of the value of data mining in solving real-world problems.
  • Understanding of foundational concepts underlying data mining.
  • Understanding of algorithms commonly used in data mining tools.
  • Ability to apply data mining tools to real-world problems.

Learning Outcomes

By the end of the module, the student should

  • Display a comprehensive understanding of different data mining tasks and the algorithms most appropriate for addressing them.
  • Evaluate models/algorithms with respect to their accuracy.
  • Demonstrate capacity to perform a self directed piece of practical work that requires the application of data mining techniques.
  • Critique the results of a data mining exercise.
  • Develop hypotheses based on the analysis of the results obtained and test them.
  • Conceptualise a data mining solution to a practical problem.
