| Outline of Final Research Achievements |
Personality structure was analyzed by statistical techniques in signal processing and machine learning. Analyses were conducted on data obtained by personality-trait scales or on descriptions about personality of famous people using independent component analysis． Factors or dimensions similar to big-five personality factors were obtained from these analyses. Analyses were also conducted on descriptions about familiar friends using nonnegative matrix factorization, and interpretable personality dimensions were obtained. These results show that independent component analysis and nonnegative matrix factorization are effective for analyzing personality structure.
