A depression diagnosis system that uses multi-paradigm electroencephalography (EEG) and machine learning to distinguish between depressed and normal states. The system measures multiple types of EEG signals from a subject, extracts and preprocesses the necessary signals to minimize noise, generates a diagnostic model using machine learning, and diagnoses depression using the model. The extracted signals include steady-state EEG, P3 waves induced by sound stimulation, and LDAEP waves. This multi-paradigm EEG approach aims to provide more comprehensive and accurate depression diagnosis compared to using a single EEG signal type.

Using generative adversarial networks (GANs) to predict changes in behavior, physiology, and well-being due to starting a new job or other stressful life event. The GANs are trained using wearable sensor data and self-reported assessments to generate predictions of feature changes. These predictions are then analyzed to identify indicators of resilience, i.e., maintaining mental health during stress. The GANs use multi-task learning with separate discriminators for features and clusters to improve performance on complex, multivariate datasets.

Automated automatic monitoring of mental health state of users based on data acquired through a mobile computing device. The automated monitoring includes obtaining data from a sensor or user-interface of a mobile computing device gathered during use of the mobile computing device by a user, inferring, from the data, with a trained machine learning and/or artificial intelligence (AI) model, a mental-health state of the user; and storing the mental health state in memory.

Diagnosing mental disorders using encephalography (EEG) signals and deep learning. The method involves feeding EEG signals from a patient into a trained neural network to classify them as having a specific mental disorder like depression, bipolar disorder, or schizophrenia. The network learns discriminative features from the EEG signals to accurately diagnose the disorders. It can also identify subtypes of disorders like treatable depression. This allows objective, neuroimaging-based diagnosis of mental disorders using EEG signals and deep learning models.

Improving the accuracy of estimating a person's psychological state by analyzing their mood over time. The method involves calculating probabilities of mood transitions and average persistence times based on historical mood data. These metrics are then learned by a neural network to estimate psychological states. This allows identifying which specific mood transitions and durations have the strongest influence on psychological well-being, beyond just overall mood statistics.

Diagnosing mental disorders with improved reliability using fuzzy techniques. The method involves obtaining a diagnostic sheet result, deriving symptoms from it, treating them with an artificial neural network, diagnosing if the user has a disorder based on the symptoms and a first disease code, and re-diagnosing using the network again if initial diagnosis is positive. Learning is done using fuzzy hierarchical and decision tree algorithms. This iterative, multi-step diagnosis process improves reliability for mental disorders where initial and late symptoms differ or not all symptoms appear.
