It is found that female gamers were more appreciative of complex behaviors than male gamers, and if game designers want players to perceive these characters in a certain way, they should consider the gender of targeted players.
Intentional Control of Type I Error Over Unconscious Data Distortion: A Neyman–Pearson Approach to Text Classification
- Lucy Xia, Richard Zhao, Yanhui Wu, Xin Tong
- Computer Science
- 7 February 2018
This article addresses the challenges in classifying textual data obtained from open online platforms, which are vulnerable to distortion and proposes the use of the Neyman–Pearson (NP) classification paradigm, which minimizes Type II error under a user-specified Type I error constraint.
