Towards a Measure of Trustworthiness to Evaluate CNNs During Operation

Due to black box nature of Convolutional neural networks (CNNs), the continuous validation of CNN classifiers' during operation is infeasible. As a result this makes it difficult for developers or regulators to gain confidence in the deployment of autonomous systems employing CNNs. We introduce the trustworthiness in classification score (TCS), a metric to assist with overcoming this challenge. The metric quantifies the trustworthiness in a prediction by checking for the existence of certain features in the predictions made by the CNN. A case study on persons detection is used to to demonstrate our method and the usage of TCS.
