Uncertainty-Wizard: Fast and User-Friendly Neural Network Uncertainty Quantification

Michael Weiss, Paolo Tonella

Uncertainty and confidence have been shown to be useful metrics in a wide variety of techniques proposed for deep learning testing, including test data selection and system supervision. We present uncertainty-wizard, a tool that allows to quantify such uncertainty and confidence in artificial neural networks. It is built on top of the industry-leading tensorflow.keras deep learning API and it provides a near-transparent and easy to understand interface. At the same time, it includes major performance optimizations that have been evaluated in several software testing use-cases on a common benchmark.
