From: Predicting the Big Five personality traits from handwriting
Type of training samples | Type of test samples | Number of training samples | Recognition rate (%)—Openness to Experience | Recognition rate (%)—Conscientiousness | Recognition rate (%)—Extraversion | Recognition rate (%)—Agreeableness | Recognition rate (%)—Neuroticism | Recognition rate (%)—overall (Undefined excluded) | Average % of cases where personality traits were Undefined | Average number of handwritten rows analyzed until the neural networks converge to a result |
