If Youden's index Y, i.e., true positive rate minus false positive rate, is maximal, then the classification accuracy cannot be further improved by taking a larger cutoff [19]. We observe Ymax ≈ 0.644 for c ≤ 0.15. Hence, a further increase of c leads to a worse proportion of correctly and falsely classified alignments. However, a large value of c assures that the predicted reading direction is with high probability the correct reading direction, see Table 1 and the r.h.s. of Fig. 5.","tracks":[{"project":"2_test","denotations":[{"id":"17540014-15405679-1690052","span":{"begin":288,"end":290},"obj":"15405679"}],"attributes":[{"subj":"17540014-15405679-1690052","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93d2ec","default":true}]}]}}
