Verification and validation of deep learning based autonomous systems


Project Description

AI based vision recognition and decision making systems are being employed in a number of application domains including cyber physical systems, medical imaging, security, and autonomous systems. The development and application of deep learning approaches in these systems have in recent years become very sophisticated, partly due to advances in deep leaning techniques, and partly due to advances in hardware acceleration and support. However their employment in safety-critical and high reliability applications is restricted for two reasons. Firstly, traditional Software Engineering verification and validation (V&V) approaches do not readily extend to the black-box nature of these systems. Secondly, there are no guarantees of false positives or negatives, and attempts to correct, or to continue to learn in a deployed system, break all classical V&V processes.

UK industrial strategy promises the deployment of autonomous vehicles in some capacity on UK roads by 2021. However the sector is still understanding how safety and reliability of autonomous vehicles will be regulated and enforced, and what V&V technologies are needed to support this.

The significant challenges facing autonomous vehicle V&V can be summarised in two distinct points. Firstly, no precise specification for safety exists – while reduced number of road deaths is a primary goal, it is not in itself a formal specification. Secondly, variation in operating environments is unconstrainable. For instance subtle changes in circumstance that are easily human detectable such as a small child meandering near a crossing can lead to massively different scenarios to a vision recognition and decision making systems.

This project will investigate the sensitivity of a deep learning vision recognition system to subtle changes in test case scenario presentation. The goal of the project is two fold: Firstly, to objectively quantify the differences in scenarios (presented in an open source format) that impact on overall safety case analysis. Secondly to develop an insight into the limits of scenario based (simulation) testing and validation for safety-critical applications and objectively demonstrate these limitations.
