Audio and cardiac based sleep-related event detection

Disclosed is a method for training a sleep-related event detection model, a corresponding method of sleep-related event detection as well as a corresponding computer program, data structure and data processing device. The training method may comprise a step of providing, as input, a set of training data samples. Each training data sample may comprise one or more cardiac signals representative of a cardiac parameter of a subject, one or more audio recording signals representative of an environmental sound of the subject and at least a first and second sleep-related event of the subject associated with the one or more cardiac and audio recording signals of the subject. The method may comprise a step of training the sleep-related event detection model using the input.
