Systems, methods, and devices for measurement, identification, and generation of sleep state models

A device comprising:

• an interface configured to obtain a plurality of measurements from a brain of a user;
• a processor configured to generate a sleep state model associated with the user, the sleep state model identifying characteristics of a plurality of sleep stages, and further identifying characteristics of transitions between the plurality of sleep stages;
• and
• a controller comprising one or more processors configured to generate a control signal based on the sleep state model and the plurality of measurements.

A method comprising:

• receiving, via an interface coupled to a brain of a user, a plurality of measurements from the user;
• identifying, using one or more processors of a processing device, based, at least in part, on the plurality of measurements, a plurality of sleep stages of the user;
• and
• generating, using one or more processors of the processing device, a sleep state model associated with the user, the sleep state model identifying characteristics of each of the plurality of sleep stages, and further identifying characteristics of transitions between the plurality of sleep stages.
