Random forest as one-class classifier and infrared spectroscopy for food adulteration detection

Autor: Felipe Bachion de Santana, Waldomiro Borges Neto, Ronei J. Poppi

Publikováno v: Food Chemistry. 293:323-332

This paper proposes the use of random forest for adulteration detection purposes, combining the random forest algorithm with the artificial generation of outliers from the authentic samples. This proposal was applied in two food adulteration studies:
