Summary: This post tries to fit Fault Tree Analysis and CDV-based “normal” bug-finding into the same conceptual framework. FTA and CDV have a challenging, uneasy relationship with each other. In a nutshell (details below): FTA (and similar techniques) is a good, established way to reason about failures and reliability, but (1) it depends on humans … More About faults and bugs
Summary: In this post I discuss the problem (common in autonomous systems verification) of checking things which don’t have “sharp” Boolean rules. I also suggest some (imperfect) solutions. Say we want to create a growing catalog of Autonomous Vehicles scenarios, and use it to test our AV, as I suggested here. We are talking system-level … More Checking probabilistic components
Summary: This post discusses one of the verification implications of the next 20 years of automation on verification: The problem of trying to predict how people will react to change. A previous post (and another one) discussed the next 20 years of automation and their general implications. This follow-up post discusses one of the … More Future of verification: Better ways to predict behavior
Summary: This post talks about some implications of the Tesla autopilot crash, claims that some autonomous vehicle fatalities are unavoidable, and suggests some ways to minimize them. By now you have probably heard about the Tesla fatal autopilot accident, causing the tragic death of a Tesla enthusiast. There is a lot of discussion about what … More The Tesla crash, Tsunamis and spec errors
