Many-Objective Reinforcement Learning for Online Testing of DNN-Enabled Systems

no code implementations27 Oct 2022 Fitash Ul Haq, Donghwan Shin, Lionel Briand

However, the environmental variables (e. g., lighting conditions) that might change during the systems' operation in the real world, causing the DES to violate requirements (safety, functional), are often kept constant during the execution of an online test scenario due to the two major challenges: (1) the space of all possible scenarios to explore would become even larger if they changed and (2) there are typically many requirements to test simultaneously.

Can Offline Testing of Deep Neural Networks Replace Their Online Testing?

no code implementations26 Jan 2021 Fitash Ul Haq, Donghwan Shin, Shiva Nejati, Lionel Briand

Further, we cannot exploit offline testing results to reduce the cost of online testing in practice since we are not able to identify specific situations where offline testing could be as accurate as online testing in identifying safety requirement violations.

Comparing Offline and Online Testing of Deep Neural Networks: An Autonomous Car Case Study

no code implementations28 Nov 2019 Fitash Ul Haq, Donghwan Shin, Shiva Nejati, Lionel Briand

Further, offline testing is more optimistic than online testing as many safety violations identified by online testing could not be identified by offline testing, while large prediction errors generated by offline testing always led to severe safety violations detectable by online testing.
