Neuron coverage-guided fuzz testing (NCFT) has become an effective whitebox testing approach for testing DNN, which iteratively generates new test cases with the guidance of neuron coverage to explore different logics of DNN, and has found numerous defects. However, existing NCFT approaches ignore that the role of neurons is distinct for the final output of DNN. Given an input, only a fraction of neurons determines the final output of the DNN.

In order to prioritize the detection of potential defects of critical neurons, we propose a fuzz testing framework, named CriticalFuzz, which mainly contains the energy-based test case generation and the critical neuron coverage criteria. The energy-based test case generation has the capability to produce test cases that are more likely to cover critical neurons and involves energy-based seed selection, power schedule, and seed mutation.
