If we don’t exactly know what we are testing, how can we test? In my previous algorithm test engineering article, I discussed the testing and analysis of more classical algorithms, such as binary search. While the overall testing of algorithms can be complicated, most classical algorithms can be described as having quite clearly defined inputs, outputs, […]

Recently I had a discussion about what it means to test an algorithm, or what it means to do algorithm test engineering. I couldn’t quite come up with a convincing definition for myself. At a basic level, maybe you figure out some basic rules of the algorithm, give it some input and output. Check the results. But I believe there is more to it, and this is what I explore in this article.

aditional software. With traditional software, the specification and its relation to the implementation is typically quite explicit. With more complex machine learning-based system, this relation is harder to explicitly define. This makes testing them more complicated. In this article, I present an updated version of my earlier work on using metamorphic testing for ML based systems.

Practical examples of applying machine learning seem to be a bit difficult to find. So I tried to create one for a presentation I was doing on testing and data analytics. I made a review of works in the area, and just chose one for illustrate. This one tries to predict a target category to […]
