Some recent visual-based relocalization algorithms rely on deep learning methods to perform camera pose regression from image data. This letter focuses the loss functions that embed error between two poses based regression. Existing are either difficult-to-tune multi-objective or present unstable reprojection errors ground truth 3D scene points and require a two-step training. To deal with thes...

The common consideration on economic model is that there is knowledge about the risk of occurrence of an assignable cause and the various cost parameters that does not always adequately describe what happens in practice. Hence, there is a need for more realistic assumptions to be incorporated. In order to reduce cost penalties for not knowing the true values of some parameters, this paper aims ...

The target costing technique, mathematically discussed by Sauers, only uses the p C index along with Taguchi loss function and X -R control charts to setup goal control limits. The new specification limits derived from Taguchi loss function is linked through the p C value to X -R control charts to obtain goal control limits. In this study, the target costing technique is exploited by further co...
