Utilizing machine learning and cognitive state analysis to track user performance

A performance management method comprises; receiving performance data about the performance of a user during an activity session; receiving media data from a user device about the activity; processing, using a cognitive state analysis model, the media data to determine a cognitive state score of the user in relation to the activity; processing, using a performance analysis model, the cognitive state score and performance data to generate a performance profile; determining a recommendation associated with the activity; and performing an action associated with the recommendation. The performance analysis model comprises a machine learning model trained using historical performance data and historical cognitive state scores. The activity may be physical exercise or a sports-based activity. The performance data may be captured by a sensor in a device worn by the user, and might measure physiological metrics of the user during the activity session. The media data may include content about the user preparing for, performing and reflecting on the activity session. The cognitive state score may be an evaluation of the emotions, sentiment or feelings the user has about the activity.
