摘要： A sleep state of a sleeping person is accurately inferred by taking into account the fact that the core body temperature affects sleep. A learning apparatus (30) learns a quality of sleep of a sleeping person. The learning apparatus (30) includes an acquisition unit (31), a learning unit (32), and a generation unit (33). The acquisition unit (31) acquires, as a state variable, a feature quantity related to a core body temperature of the sleeping person or a feature quantity related to a skin temperature of the sleeping person. The feature quantity related to the core body temperature is determined based on at least a first core body temperature at sleep onset of the sleeping person. The feature quantity related to the skin temperature is determined based on at least a first skin temperature at the sleep onset of the sleeping person. The learning unit (32) learns the state variable and the quality of sleep in association with each other. Based on a learning result of the learning unit (32), the generation unit (33) generates a learning model. The learning model receives, as an input, the feature quantity related to the core body temperature or the feature quantity related to the skin temperature of the sleeping person and outputs the quality of sleep.

摘要： Biological information such as a heart rate, which is acquired using an apparatus such as a wearable sensor, has a large error, and information estimated based on the biological information may have low accuracy. A system includes a first acquisition unit (11), a second acquisition unit (21), and an estimation unit (13, 23, 32). The first acquisition unit (11) acquires first biological information of a target. The first acquisition unit (11) is constituted by one or more sensors. The second acquisition unit (21) acquires second biological information of the target. The second acquisition unit (21) is constituted by one or more sensors different from the one or more sensors of the first acquisition unit (11). The estimation unit (13, 23, 32) estimates a first thermal comfort of the target on the basis of the first biological information. The estimation unit (13, 23, 32) estimates a thermal comfort of the target on the basis of the first biological information and the second biological information. When the second acquisition unit (21) does not acquire the second biological information, the estimation unit (13, 23, 32) sets, as the thermal comfort of the target, the first thermal comfort that is corrected on the basis of the second biological information previously acquired by the second acquisition unit.
