Recent advances in the verification of deep neural networks (DNNs) have opened the way for broader usage of DNN verification technology in many application areas, including safety-critical ones. DNN verifiers are themselves complex programs that have been shown to be susceptible to errors and imprecisions; this in turn has raised the question of trust in DNN verifiers. One prominent attempt to address this issue is enhancing DNN verifiers with the capability of producing proofs of their results that are subject to independent algorithmic certification (proof checking). Formulations of proof production and proof checking already exist on top of the state-of-the-art Marabou DNN verifier. The native implementation of the proof checking algorithm for Marabou was done in C++ and itself raised the question of trust in the code (e.g., in the precision of floating point calculations or guarantees for implementation soundness). Here, we present an alternative implementation of the Marabou proof checking algorithm in Imandra -- an industrial functional programming language and prover -- that allows us to obtain an implementation with formal guarantees, including proofs of mathematical results underlying the algorithm, such as the use of the Farkas lemma. |
