Summary: I discussed before (e.g. here) how connecting rule-based verification to the rule-less, amorphous Machine Learning world is really hard, and yet necessary. The current post talks about a somewhat-exotic technique called Program Induction (PI), and how it might (eventually) help bridge that gap. What’s program induction Background: I always liked the idea of synthesizing … More Using program induction for verification
Summary: This is a short collection of some news / papers related to Autonomous Vehicles verification Some info about how Waymo does verification: The Atlantic came out with a long article about how Waymo verifies AVs. I did not see much which was new or unexpected here (but I assume they did not divulge their … More AV verification updates: Waymo, Apple and more
Summary: This is part two of my report about what I saw at the Stuttgart 2017 Autonomous Vehicles test & development symposium. It covers frameworks, simulators, scenario definitions and extracting scenarios from recordings. As I promised in part one, here is the rest of my trip report from that yearly symposium. It will cover the … More What’s new in AV verification: Stuttgart report part two
Summary: This post addresses some high-level questions like: Longer term, how much of the verification of Intelligent Autonomous Systems can be done with just Machine Learning (ML)? Should most requirements remain rule-based, and if so – how does that connect to the ML part? And how will the uneasy interface between ML and rules influence … More Where Machine Learning meets rule-based verification
Summary: This post will talk about “One-shot imitation learning” (a new and exciting direction in Machine Learning), and how that direction could help coverage maximization (which is important for verification). It will then speculate about the general role of ML in Intelligent Autonomous Systems verification. Note: You may have heard already about one-shot imitation learning … More One-shot imitation learning and verification
Summary: This post tries to explain (once and for all?) how the concept of coverage is used to optimize the verification process, what it means to auto-maximize coverage, and how people have tried to do it. I have been spending some time lately on coverage maximization via ML (which I described here). As is often … More Verification, coverage and maximization: The big picture
Summary: Can one use ML to verify ML-based systems? This post claims the answer is mostly “no”: You mainly have to use other system verification methodologies. However, some ML-based techniques may still be quite useful. How does one verify ML-based systems? A previous post in this series claimed that the “right” way is CDV: Essentially, … More Using Machine Learning to verify Machine Learning?
Summary: This post describes in general terms the problem of “using ML for coverage maximization”, explains why it is important for CDV and for fuzzing, and gives some references. My first post in the “ML and verification” series talked about verifying ML-based systems (lots more to say about that). This post talks about the other … More Machine Learning for Coverage Maximization
