This exciting course broaches the hot topic of Data Analysis and Knowledge Discovery (DAKD) from the viewpoint of Data Mining.
Most areas in science, engineering and business are becoming increasingly data dependent. Clear examples of this are, to name a few, bioinformatics, medicine, or electronic commerce.
Data analysis techniques are needed to deal with these data and generate usable knowledge out of them. Amongst them, DAKD techniques are one of the most promising approaches. This theme is at the core of the contents of this course.

Objectius

  1. Presenting DM as a process that should involve a methodology id applied at its best.
    Competències relacionades: CG3, CTR4, CTR6,
  2. Introducing the students to the new concept of DM for processes, called Process Mining.
    Competències relacionades: CG3, CEC3, CTR6,
  3. Delving into some detail in one of the stages of DM: data exploration.
    Competències relacionades: CTR4, CTR6,
  4. Dealing in detail with the problem of data visualization for exploration as a key issue in DM.
    Competències relacionades: CTR4, CTR6,
  5. Introducing the students to the basics of probability theory as applied in Data Analysis and Knowledge Discovery (DAKD)
    Competències relacionades: CEC1, CTR4, CTR6,
  6. Introducing the students to the probabilistic variant of DAKD in the form of Statistical Machine Learning, both for supervised and unsupervised learning models.
    Competències relacionades: CEC1, CTR4, CTR6,
  7. Dealing in detail with different unsupervised models for data visualization, including case studies.
    Competències relacionades: CG3, CTR4, CTR6,
  8. Approaching the multi-faceted concept of data mining (DM) from different perspectives.
    Competències relacionades: CG3, CTR4,

Continguts

  1. Introduction to the concept of data mining (DM).
    DM is a multi-faceted concept that requires discussion and clarification. We will do this at the beginning of the course.
  2. DM as a methodology.
    We argue that DM should not be focused on the concept of data analysis/modeling, but, instead, should be treated as a methodology with diverse inter-related stages.
  3. DM for processes: Process Mining.
    A new development in DM methodologies is that which deals with one specifically suited for processes. It is called Process Mining and will be described and discussed in this course.
  4. Data exploration in DM.
    One of the main stages of well-structures DM methodologies is Data exploration. It will be discussed as a preamble to data visualization.
  5. Data visualization for exploration.
    One of the aspects of the problem of data exploration is data visualization. It has a research 'life' of its own as it involves not only computer-based mathematical models, but also natural perception and processing.
  6. Basics of probability theory in Data Analysis and Knowledge Discovery (DAKD)
    For a long time in the last half-century, multivariate statistics and artificial intelligence (mostly in the field of machine learning) have developed in parallel without fully meeting. Statistical machine learning has bridged that field over the last two decades. We introduce it by first providing some basic principles of probability theory (Bayesian inference).
  7. Statistical Machine Learning for DAKD: supervised models.
    Once the basics of Bayesian inference are set, we will delve into the field of Statistical Machine Learning for IDA, starting with supervised learning models, with an emphasis on feed-forward artificial neural networks.
  8. Statistical Machine Learning for DAKD: unsupervised models.
    Once the basics of Bayesian inference and of Statistical Machine Learning for IDA in supervised models are set, we will continue with unsupervised models, focusing on self-organizing maps and related models.
  9. Unsupervised models for data visualization, with case studies.
    In the final item of the contents of the course, we will bring statistical machine learning and data visualization together by discussing some probabilistic unsupervised learning models for data visualization, including some case studies as an example.
