Background

 

Software Engineering is still a young research field. Several errors are still occurring in methods and techniques applied  to empirically validate results. The errors are not only made by early research scientist but also present in the most  important conference and journal papers [1].

This seminar aims at providing a comprehensive coverage of methods and techniques to collect and analyze data in software engineering. We will cover both basic statistical methods, predictive models and Artificial Intelligence approach, including machine learning techniques. In this seminar students will learn how to apply these techniques to analyze different type of data collected during software development processes and how to draw conclusions based on these data. The seminar will be conducted by three of the leading professors in the area of empirical software engineering and in  the area of machine learning analysis. Two hands-on sessions will help students to directly apply the techniques explained during the course, one applying a  set of statistical techniques (linear and logistic regressions) and another applying classification techniques (Random Forest) on a set of data mined from open source repositories.

 

Overview

The topics covered in the seminar include:

  • Data Collection and packaging approaches in software engineering. 
    • Survey 
    • Case study 
  • Data analysis techniques in software engineering. Which method should be applied in the different contexts? 
    • Statistical methods and measurement. 
    • Machine Learning techniques 
    • Pattern recognition 
  • Drawing conclusions from results 
    • How to interpret the results obtained from the techniques applied
