Manual Model Validation A last validation step consisted of manually evaluating the outcomes. Despite the fact that we extracted statistically considerable functionality metrics in the test dataset (see above), this dataset was extracted from a single area that didn’t possess the wide variety of soil and land-use types present inside the entire with the study area. As this could considerably influence the presence of FPs (e.g., regions with isolated homes could present false positives in the type of houses’ roofs and eroded highland locations within the type of rock outcrops), a manual validation was considered necessary. This is a simple measure in archaeological detection research, in unique with respect to mound detection function, as FPs often constitute a really high proportion with the detected features (see one example is, [1,8]). For the manual visual inspection on the detected attributes, we utilized 3 various series of high-resolution imagery provided by Google, Bing, and ESRI, accessed as XYZ Tiles, a.
