Abstract: An information processing system includes: an information acquisition unit that acquires patient information indicating a state of a patient who has visited a first institution or who has been examined by a person associated with the first institution; a determination unit that determines whether or not the patient information satisfies at least one of predetermined determination conditions; and a processing control unit that, when the patient information satisfies at least one of the determination conditions, performs a process for matching a second institution included in setting-origin institutions associated with the satisfied determination condition with the patient. Each of the predetermined determination conditions is a condition for determining whether a suspicion of a predetermined disease is correct or not, and is associated with a setting-origin institution that has set that determination condition.

Abstract: A body fluid volume estimation device includes a pre-training unit, a transfer learning unit, and an estimation unit. The pre-training unit performs pre-training by using, as supervised information, information indicating body fluid volumes of the multiple patients when face images of multiple patients are captured. The transfer learning unit further performs transfer learning on multiple face images of one specific patient after the pre-training, and constructs a trained model. The estimation unit estimates, by inputting a face image of the one specific patient to the trained model, a body fluid volume at a point in time at which the face image of the one specific patient is captured. By estimating a body fluid volume from a face image by machine learning, the body fluid volume can be used for assistance such as decision making of a user.

Abstract: The stress estimation device acquires the awakening degree of the subject and calculates the feature amount of the acquired awakening degree. The feature amount of the awakening degree is, for example, a ratio at which the temporal change of the awakening degree is within a predetermined range, information defining a histogram showing the distribution of the temporal change of the awakening degree, and the like. Then, the stress estimation device estimates the stress from the calculated feature amount using the stress model.

Abstract: A stress estimation apparatus 1 acquires a biosignal of a measurement subject, which includes acceleration information of an action of at least one part of the measurement subject. A moving average is calculated from the acceleration information included in the acquired biosignal, and a threshold of an activity state of the measurement subject is calculated from the calculated moving average. Then, an activity state in a specific period is identified from the calculated moving average and the calculated threshold. Per-activity state data is generated by categorizing chronological data pieces of the acquired biosignal other than the acceleration information by identified activity state, and stress is estimated from the generated per-activity state data.
