Different metrics of the ANN on the PMS category vs. different sizes of the other objects category. Stabilisation point is marked with a vertical grey line. Top: precision and recall. As the size of the category gets larger the recall drops drastically up to the stabilisation point whereas the precision is roughly stable at all sizes. Middle: TP, FP, and FN. Similarly, TP and FN have equal stabilisation point whereas FP is stable for all sizes. Bottom: number of PMS candidates obtained when generalizing the trained ANN, we note the same stabilisation point.
