A Confidence Index Based Test Approach for AI Systems

The tutorial is based on our research and experiments with Buick LaVida effective real claim cases for car damage, we designed an intelligent claim evaluation generation model based on a multi-layer deep learning algorithm. Addition to the traditional risk-based analysis testing, we designed a confidence index approach to manage the risk associated with the “black-box” nature of the AI system. The proposed confidence index could be computed as either statistic or machine learning methods, in which considering the following factors, such as

1) historical data coefficient of variation,

2) data convergence degree, and

3) data item similarity.

It has been applied to predict the automotive body parts replacement and labor cost based on deep learning algorithms, which effectively control the potential risks by unrecognized cases caused AI system failure.
