Lunch seminar: Test Case Selection In The Presence of Class Noise: A Controlled Experiment
Theme 3 (Metrics) invites to the next brown bag seminar about the machine learning-related topics. This week we have Khaled Al-Sabbagh presenting his work on the reduction of class noise. Machine learning models have been increasingly used to support decision making in software engineering tasks. One example of its application is the optimization of test case selection in continuous integration. Among the challenges that hinders the application of machine learning is the amount of noise that comes in the data,…

Data Labeling: Industrial Challenges and Mitigation Strategies Labels are a prerequisite to perform supervised machine learning. However, in industrial contexts, data is often incomplete because labels are missing partially or entirely. Even if there exist manual, semi-automatic, and automatic techniques, such as crowdsourcing, active-learning (AL), and semi-supervised learning (SSL), we have seen that AL and SSL are rarely implemented due to lack of knowledge of their existence. Furthermore, labeling instances manually is not optimal as it is time-consuming and challenging…

Find out more »Lunch seminar: Are you using the MNIST dataset to compare the algorithms?
Presenter: David Issa Mattos (PhD student, Chalmers) One of the most common tasks when developing a new tool is to benchmark it against competing tools. Both researchers and practitioners often look at the results of these benchmarks before selecting the appropriate tool. However, the quality of the benchmark greatly influences the results. In this presentation, we discuss how to evaluate if your benchmark has the appropriate difficulty level and is capable of differentiating the competing tools. We make an analogy…

Deep neural networks trained on source code have been shown to automate routine development tasks such as code completion, comments generation, etc. But is such an AI expert in coding also an expert in software design? With design often being considered as a specialist skill, what do we do to ensure that the model understands nuances of SW design? Ensuring this opens up possibilities of automating design-related tasks. This talk will introduce our first experiments in taking a deep learning…

Find out more »Lunch Seminar: Generating Exception-Triggering Tests
Speaker: Gregory Gay, Chalmers Abstract: Search-based test generation is guided by feedback from one or more fitness functions—scoring functions that judge solution optimality. Choosing informative fitness functions is crucial to meeting the goals of a tester. Unfortunately, many goals—such as forcing the class-under-test to throw exceptions—do not have a known fitness function formulation. We propose that meeting such goals requires treating fitness function identification as a secondary optimization step. An adaptive algorithm that can vary the selection of fitness functions could adjust its selection throughout the generation process to…
