Experiments

Schwa is created in a context of research therefore, we must validate our hypothesis with data. There are two main Research Questions:

• RQ1: What are the most important features and their importance (weights)?
• RQ2: Can we decrease the diagnostic cost of Crowbar by using Schwa defect probabilities?

Learning Features (RQ1)

Considering that Schwa outputs a rank, our goal is to compute a probability from Revisions, Fixes and Authors tracked information, so that faulty components have more defect probability that non-faulty components. We call this the distance. By using, Genetic Algorithms, we encoded an individual as {RevisionsWeight, FixesWeight, AuthorsWeight} and the fitness function is distance({RevisionsWeight, FixesWeight, AuthorsWeight}}.

Results

The following tables are the results of running the Genetic Algorithm in a variety of projects, from Open Source to enterprise. The bits precision is 3 and the number of generations is 40. Be aware that, solutions with fitness=0 are not trustable, because they can have more than one solution (individuals) that are 0.

Crowbar Diagnostic Cost (RQ2)

The diagnostic cost can be described as the average distance a faulty component is from the top of the rank. It is the average because components with the same score can change their positions on the rank, if you run Crowbar multiple times.
