[4] compared RTVTR, ridge count, white lines count, ridge count asymmetry and pattern type concordance as features. By adding a degree of bias to the regression estimates, ridge regression reduces the standard errors. In addition to publishing its own journals, the division also provides traditional and digital publishing services to many client scholarly societies and associations. Gender classification from fingerprint ridge count and fingertip size using optimal score assignment, $$ {\text{RC}} = a + \frac{1}{2}\left( {b + c} \right). They are given by following pattern type. In the early 1900s, the system was no longer effective for the effective searching of fingerprints. Therefore, it is used as purpose for personal identification.

If the male score (MS) is higher than the female score (FS), the decision is declared as male, otherwise it is declared as female. If there is whorl pattern found on the thumb then ridge tracing will be done. The ridge counting of the whorls in the final classification is very rarely used.
