Videos • Healthy control subject http://youtu.be/4aFMQFhiRHw • Patient with schizophrenia http://youtu.be/-TECG5XQhB4
Classification by Logistic Regression • 3 dimensional feature space: • Ensemble right hemispheric synchronization. • Ensemble left hemispheric synchronization. • Response latency.
2 Dimensional Projection of 3 Dimensional Feature Space Cross is patient with schizophrenia square is healthy control subject Incongruent stimulus
2 Dimensional Projection of 3 Dimensional Feature Space Congruent stimulus Plus is patient with schizophrenia circle is healthy control subject
2 Dimensional Projection of 3 Dimensional Feature Space Neutral stimulus Star is patient with schizophrenia diamond is healthy control subject
