    Abstract: Systems and methods for utilizing machine learning to generate a trans-diagnostic classifier that is operative to concurrently diagnose a plurality of different mental health disorders using a single trans-diagnostic questionnaire that includes a plurality of questions (e.g., 17 questions). Machine learning techniques are used to process labeled training data to build statistical models that include trans-diagnostic item-level questions as features to create a screen to classify groups of subjects as either healthy or as possibly having a mental health disorder. A subset of questions are selected from the multiple self-administered mental health questionnaires and used to autonomously screen subjects across multiple mental health disorders without physician involvement, optionally remotely and repeatedly, in a short amount of time.

    Abstract: A system for facial analysis includes a camera, a data storage device and a data processing system. The camera takes video of a subject's face, and the data storage device receives and stores the video. The data processing system extracts a pose of the subject's face, and a representation of the subject's facial gesture state. The pose includes the angle and position of the subject's face. The representation includes facial keypoints that are a collection of points on the subject's face. The system then concatenates each data stream to align the data streams in time, extracts a plurality of facial syllables from the aligned data streams, and compiles the facial syllables into a series of state sequences. Based on the series of state sequences, the system extracts a behavioral fingerprint for the subject that provides a summary of the subject's state over a given period of time.
