Abstract: An information processing system includes: a machine learning model learned using learning data including two or more types of modal information acquired from a patient or a subject; a setting unit that sets input data to be used as input to the machine learning model from the learning data; and an output unit that inputs the input data to the machine learning model and outputs an estimation result of efficacy of a medicine or a health condition for the patient or the subject, in which the setting unit sets the input data on the basis of the degree of influence given to estimation of a diagnosis result at the time of learning of the machine learning model, the degree of influence given by each piece of the modal information included in the learning data.

Abstract: A first block storage device sharing an object storage device with a second block storage device has: plural kinds of physical devices having different access response performances; and a hierarchical logical disk created by using the storage areas of the physical devices and the storage area of the object storage device. When the access frequency of a logical block stored in a hierarchy one level above a lowest hierarchy falls below a threshold, the first block storage device searches the object storage device for a logical block having the hash of the logical block as a content address. When the search fails, the first block storage device transmits the logical block to the object storage device to change a hierarchy to store the logical block to the lowest hierarchy, whereas when the search succeeds, omits the transmission and changes a hierarchy to store the logical block to the lowest hierarchy.
