  • Publication number: 20240021192
    Abstract: System and method for detecting cognitive decline in a subject using a classification system for detecting cognitive decline in the subject based on a speech sample. The classification system is trained using speech data corresponding to audio recordings of speech from normal and cognitive decline patients to generate an ensemble classifier comprising a plurality of component classifiers and an ensemble module. Each of the plurality of component classifiers is a machine-learning classifier configured to generate a component output identifying a sample data as corresponding to a normal patient or a cognitive patient. The machine-learning classifier is generated based on a subset of available features. The ensemble module receives component outputs from all of the component classifiers and generates an ensemble output identifying the sample data as corresponding to a normal or cognitive decline patient based on the component outputs.

  • Publication number: 20230245773
    Abstract: A system and computer-implemented method for detecting return of depression of a patient is provided. The system comprises a wearable device configured to detect movement of the patient and configured to generate actigraphy data corresponding to the movement of the patient and a computing device for retrieving actigraphy data from the device. The system and method obtain training data, including training actigraphy data, over a training period and train an anomaly detector using the training data. The system and method subsequently obtain test data from the patient, extract a plurality of features from the test data, and analyze the extracted data using the trained anomaly detector. A self-report test is used to determine whether an anomaly identified by the anomaly detector indicates that the patient is likely to experience return of depression.
