DeepSaucer: Unified Environment for Verifying Deep Neural Networks
In recent years, a number of methods for verifying DNNs have been developed.
Because the approaches of the methods differ and have their own limitations, we
think that a number of verification methods should be applied to a developed
DNN. To apply a number of methods to the DNN, it is necessary to translate
either the implementation of the DNN or the verification method so that one
runs in the same environment as the other. Since those translations are
time-consuming, a utility tool, named DeepSaucer, which helps to retain and
reuse implementations of DNNs, verification methods, and their environments, is
proposed. In DeepSaucer, code snippets of loading DNNs, running verification
methods, and creating their environments are retained and reused as software
assets in order to reduce cost of verifying DNNs. The feasibility of DeepSaucer
is confirmed by implementing it on the basis of Anaconda, which provides
virtual environment for loading a DNN and running a verification method. In
addition, the effectiveness of DeepSaucer is demonstrated by usecase examples
Policing functions for machine learning systems
Machine learning (ML) systems typically involve complex decision making mechanisms while lack clear and concise specifications. Demonstrating the quality of ML systems therefore is a challenging task. We propose an approach combining formal methods and metamorphic testing for improving the quality of ML systems. In particular, our framework enables the possibility of developing policing functions for runtime monitoring ML systems based on metamorphic relations
