We used in order to understand how the variables are influenced by other factors and to what extent they are related to each other, As an application for this great technology in this project detecting olive origin would be great example for how to use these technologies, classification by Principle component analysis (PCA), and partial least square regression (PLSR) are used along with this application.enOctober university for modern sciences and artsuniversity of modern sciences and artsجامعة اكتوبر للعلوم الحديثة و الادابMSA universityOther
