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
