Data Science for Security and Forensics
Study plans 2016-2017 - IMT4133 - 7.5 ECTS

On the basis of

BSc level basics in statistics and mathematics, i.e. expected prior-knowledge in understanding basic statistical methods like descriptive statistics, probability, sampling distributions, and hypothesis testing, as well as basic analysis and matrix algebra.
 

Expected learning outcomes

Knowledge:

  • Understand principles how multidimensional statistical methods differ from one dimensional methods.
  • Understand the distribution of information in statistical analysis and meaning in data representation.
  • Extract features from raw, measured values of data to be analyzed.
  • Program some basic classification and clustering methods and test their validity.
  • Program some basic Neural networks methods and test their validity.
  • To apply basic statistical and data analysis methods to data relevant in information security, forensics and/or color/media technology

Skills:

  • The students can use relevant scientific methods in independent research and development in machine learning and pattern recognition.
  • The students are capable of carrying out an independent limited research or development project in machine learning and pattern recognition under supervision, following the applicable ethical rules.

 General competence:

  • The students can work independently and are familiar with terminology of machine learning and pattern recognition as well as their application in the security and forensics domain.

Topic(s)

 

  • Learning, Intelligence, and Machine learning basics: principles, measures, performance evaluation, method combinations.
  • Knowledge representations: discriminant and regression functions, probability distributions, Bayesian classifier.
  • Learning as search: Exhaustive search, heuristic search, genetic algorithms.
  • Attribute quality measures: measures for classification, measures for regression, application of feature-selection measures.
  • Data preprocessing: Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA).
  • Supervised symbolic and statistical learning, basics of artificial neural networks.
  • Unsupervised Learning and cluster analysis: hierarchical and partial clustering.
  • Data classification: Bayesian classifier, k-NN classifier, multi-layered perceptron (MBPN), support vector machine (SVM), and Random Forrest.
  • Data clustering: k-means clustering, Self-Organizing map (SOM).
  • Classification and clustering validity testing: leave-one-out, ground truth.
  •  Practical tasks may include:
    • Realize some search methods
    • Realize some classification methods
    • Realize some clustering methods
