Table 3 Big Five personality prediction accuracies and average number of rows in inter-subject tests
From: Predicting the Big Five personality traits from handwriting
Type of training samples | Type of test samples | Number of subjects involved in training | 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 network converges to a result |
