I study the influence of face perception on socio-sexual behaviors in Mandrill (Mandrillus sphinx), a primate from Central Africa, relying on a long-term research program on a wild population of more than 300 mandrills launched in 2012 in Gabon. (Mandrillus Project). To model the perception of face, I will use tools from deep learning on a database of pictures portraying individuals of the
studied population.
