The Gini index does not give a strictly consistent scoring function. Therefore, simply maximizing the may lead to wrong model choice. main issue is that rank-based score calibration-sensitive. We show allows for if we restrict it class of auto-calibrated regression models. That is, on models know true maximizes index.

We developed SPECT imaging capability on an animal PET scanner to provide a cost effective option for animal SPECT imaging. The SPECT add-on sub-system was enabled by mechanically integrating a multiple-pinhole collimator in the PET detector ring. This study introduces a method to calibrate the geometrical parameters of the SPECT add-on using the PET imaging capability of the scanner. The propo...

The dynamics of a moving train are usually described by means motion model based on Newton’s second law. This uses as input track geometry data and characteristics like mass, the parameters that running resistance, maximum tractive effort power, brake rates to be applied. It can reproduce predict accurately if mentioned carefully calibrated. constitutes core element broad variety railway applic...
