    Abstract: The disclosed technology is directed to improvements in multi-modal and multi-sensor diagnostic devices, that utilize machine learning algorithms to diagnose patients based on data from different sensor types and formats. Current machine learning algorithms that classify a patient's diagnosis focus on one modality of data output from one type of sensor or device. This is because, among other reasons, it is difficult determine which modalities or features from different modalities will be most important to a diagnosis, and also very difficult to identify an algorithm that can effectively to combine them to diagnose health disorders.

    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.
