One-shot imitation learning and verification

May 25, 2017

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

Misc stuff: Mobileye, simulations and test tracks

March 28, 2017

Summary: This is another “What’s new in verification land” post. It describes a video and a paper from Mobileye, and takes that opportunity to revisit four topics: How Autonomous Vehicles should handle unstructured human interaction, how to balance Reinforcement Learning and safety, why simulation is the main way to validate safety in these unstructured environments, … More Misc stuff: Mobileye, simulations and test tracks

Formal verification of really-complex systems

March 13, 2017

Summary: This post describes some new attempts at formal verification of complex systems (mainly AVs and ML-based systems) In general, I think Formal Verification (FV) will only have a limited role in verifying Intelligent Autonomous Systems (IAS) and ML-based systems, because those systems are so complex and heterogenous. In FV has better PR than CDV … More Formal verification of really-complex systems

Verifying interactions between AVs and people

January 26, 2017

Summary: The interactions between Autonomous Vehicles and people can be complex, which complicates AV deployment.  This post summarizes some recent related publications, and then tries to predict the verification implications of all that. For instance, it suggests that verification teams will try to track total-accidents, AV-specific-accidents and AV-specific-annoyances. There were several interesting publications lately about “bumps on … More Verifying interactions between AVs and people

The “Synthetic Sensor Input” problem in AV verification

January 17, 2017

Summary: This post discusses the annoying “Synthetic Sensor Input” (SSI) problem, i.e. the fact that it is very hard to synthesize realistic, synchronized streams of sensor inputs (e.g. Video+LiDAR+Radar). It explains why the SSI problem is a pain for Autonomous Vehicles verification (and for other things), and talks about the (imperfect) solutions. Let me start … More The “Synthetic Sensor Input” problem in AV verification

Verification, coverage and maximization: The big picture

December 23, 2016

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

Misc stuff: The verification gap, ML training and more

October 16, 2016

This post covers recent updates in machine learning, autonomous systems and verification. It has four sections: Automation / ML keep accelerating, but verification of automation / ML seems to lag behind HVC is coming, and I plan to attend (and even present) The idea of training an ML-based system using synthetic inputs (which I like) … More Misc stuff: The verification gap, ML training and more
