- | The ideal situation for stopping the iteration process is that the two Kriging results are identical, implying that all diagonal values of each table are 1 and all other values are 0. Thus two values, Bray-Curtis distance and Root-mean-square deviation (RBSD), are computed between the diagonal of the overall heat table and the diagonal of the ideal table. These two values are shown in the bottom label, and ADCI-BGQ gives a suggestion based on these two values about whether to stop/continue the iterative process. The criterion to stop the iteration is computed from the following case, which is also described in the tooltip shown when the mouse cursor hovers over the bottom label: in the overall table, every diagonal value is 90% (i.e. the area of the overlap between each region in the current Kriging result and the corresponding region in the previous result accounts for 90% of the area of either region). In this case, the diagonal Bray-Curtis distance is 1/19, which is a maximum threshold; the RBSD is 0.1, which is also a maximum threshold. As long as one of these two statistical values meets the threshold, then the software recommends to stop the iteration. | + | The ideal situation for stopping the iteration process is that the two Kriging results are identical, implying that all diagonal values of each table are 1 and all other values are 0.
