Because of different applications, different models have been proposed for the sex determination and one of these models is the cascade mathematical model that offers the desired result through approximate the data and scaling algorithm. Purpose of this study is to use these networks to detect the sex from the face. Results obtained in experiments revealed that face-based sex determination has been successful to the extent of 90%, indicating its ability to solve the issues of sex determination.
