Bed having features for automatic sensing of illness states

A system for classifying a sleeper on a bed into an illness state, the system comprising:

• a bed having a mattress;
• one or more sensors configured to:
• sense one or more physical phenomena of a sleeper on the bed;
• generate data signals based on the sensed physical phenomena;
• and
• send, to a computing system, the data signals;
• the computing system comprising one or more processors and computer memory, the computing system configured to:
• receive the data signals;
• generate, from data signals of a sleep-session of the sleeper, a feature vector of features, each feature having a feature value that represents one of the physical phenomena;
• and
• classify the sleeper into an illness state for the sleep session based on the feature vector.
