Summary: This short post does not talk about autonomous vehicles. It talks about a new paper describing new ways in which complex socio-technical systems could go bad. I then talk about the verification implications of that. Bruce Schneier is a well-known security researcher: I have been following his blog for years. I don’t mention him … More About “The coming AI hackers” paper
Summary: This post talks about GPT-3, a new Machine Learning (ML) system currently making waves in the ML community. It explains why GPT-3 is a big deal, and then considers the verification implications of such systems. One way to look at GPT-3 (and the even-bigger GPT-4, GPT-5 etc. which are sure to follow) is as … More GPT-3 and verification
Summary: This post tries to summarize what dynamic verification is, using a single picture. It then puts various verification tools, and diverse verification projects, in the context of that picture. It also explains Coverage Driven Verification (CDV). The Foretellix blog is about verifying complex systems. However, as I discussed here, there is no agreed-upon verification … More Dynamic verification in one picture
Summary: This post investigates the (slightly crazy) idea of creating “one universal verification framework for everything”, and claims that while the goal itself is probably impossible (for now), some interesting and worthwhile sub-goals are perhaps possible. As many people (including myself) have discussed before, there is no single “verification community”: there are really many verification … More Is a Universal Verification Framework possible?
This is another one of those posts devoted to misc. things which may be of interest to readers of this blog. HVC The Haifa Verification Conference 2015 is upon us (Nov 16-19). If you are in Israel at that time and have nothing better to do, here are some reasons you might want to come … More Misc. stuff: HVC, game design languages and more
In a previous post I discussed verification vs. validation, and claimed that: This is a valuable distinction for a specific subsystem, but (in any complex system) this is a subsystem-relative concept, not an absolute one (as in “one man’s ceiling is another man’s floor”). I was reminded by some readers that this view (“real systems … More The soup of systems
I got interesting comments from some [1] loyal readers of this blog, about these “examples of systems to verify” mentioned in my initial post: Some people claimed that these systems are really so different in scale that they are really incomparable. In particular, I heard the claim that hardware verification (where I spent much of … More On that “verification range” issue
I had a breakfast discussion about this simulation-for-transportation-policies with two friends of mine who have been looking into similar topics for years: Nadav Levy and Itzhak Benenson of Tel Aviv Univ. This was triggered by my post about a related topic. Here are the main things I learned during breakfast: They are interested in policies like: … More A breakfast discussion about simulations for transportation policy decision making
This somewhat-unexpected topic came up in several offline conversations during the Stuttgart symposium On day 1, I had a discussion with a guy who gave the lecture “Impact of driverless mobility on vehicle development and testing” (Thomas delos Santos, CEO, Innovative Mobility Automobile GmbH, Germany). His is a small consultancy house which consults e.g. cities … More Also from Stuttgart: Using simulation for public policy decision making
