When the rendering budget is limited by power or time, it necessary to find combination of parameters, such as resolution and refresh rate, that could deliver best quality. Variable-rate shading (VRS), introduced in last generations GPUs, enables fine control quality, which each 16×16 image tile can be rendered with a different ratio shader executions. We take advantage this capability propose ...

k Nearest Neighbor (kNN) method is a simple and popular statistical for classification regression. For both regression problems, existing works have shown that, if the distribution of feature vector has bounded support probability density function away from zero in its support, convergence rate standard kNN method, which same all test samples, minimax optimal. On contrary, unbounded we show tha...
