Event Description

Speaker: Yury Makedonov

There are two main challenges to testing systems that incorporate elements of Artificial Intelligence (AI). The same input can trigger different responses while an AI system adapts to a new environment. It may also be challenging to understand what is the correct response.

Such behavior breaks one of the main principles of traditional testing – repeatability of execution of test cases. This is akin to shooting a moving target and not knowing whether you missed. Testers feel frustrated when their traditional approach can’t be used anymore and have no confidence in the outcome of their testing.

Yury Makedonov explains that to successfully test an AI system, you need to have direct access to the system’s state. Using an example of a simplified machine learning system with a few simple models of its internals Yury shows how to use the state of this system for effective testing and how to deal with test data, the most difficult part of AI testing. You can apply these “grey box” testing techniques to a wide range of AI systems from simple machine learning systems to complex neural networks.
