Regression is one of the most commonly used statistical techniques. However, testing regression systems a great challenge because absence test oracle in general. In this paper, we show that Metamorphic Testing an effective approach to multiple linear systems. doing so, identify intrinsic mathematical properties regression, and then propose 11 Relations be for testing. Their effectiveness examin...

The near-infrared (NIR) sensor can be used for measuring the basis weight and moisture of tissue paper, but measurement accuracy is not ideal this paper grade. range 10~30 g/m2, indicating that it a low gram paper. temperature humidity production environment significantly impact an NIR sensor. This focuses on improving weight. In order to reduce influences humidity, mathematical model based par...
