Analysis of Users' Favorite Faces and Methods of Composing a Favorite Face for Each User

Abstract

In this paper, we analyzed individual face preferences. First, we examined what kinds of faces subjects chose based on their preferences. These faces were composed of shuffled parts of faces (nose, eyes, mouth, and hair) of members of AKB48, an idol group. Unexpectedly, the subjects' preferences were very different, although each face created was very cute. Regression equations were then constructed using the parts numbers as the independent variables and the evaluations of each face as the dependent variables. The results of multiple regressions showed that a user's own preferred face can be estimated from his/her preference for each part of the face. Next, we created some faces using parts of AKB48 members' faces based on each subjects' evaluation of the parts of faces in the pre-experiment. The results of the evaluation of the created faces supported previous findings. Using these results, we proposed a creation method for each user's favorite face. The experimental results showed that the proposed method can create each user's favorite face.
