Abstract: According to one embodiment of the present invention, food item information on a plurality of food items suitable for snacking classified into a plurality of clusters according to similarity in feature quantities for the shape, taste, and texture is stored. Calories less than the difference between the sum of the calorie consumption by the user during a first period before user-specified desired snacking time and expected calorie consumption during a second period thereafter and the sum of calorie intake during the first period and expected calorie intake during the second period by the user are obtained as ingestible snacking calories, and a food item having calories less than the ingestible snacking calories and belonging to a cluster other than a cluster selected for the previous snacking is selected from the food item information and presented to the user.

Abstract: The present invention includes a memory and a processor configured to store, in a storage, a first digital twin in which at least one model defining at least one function of an entity at a given time, and at least one piece of second data that includes, as a constituent element, first data for realizing the function of the entity due to being input to the model are included, create at least one second digital twin by performing predetermined first computation using, as a computation target, at least one first digital twin stored in the storage, and execute computation for arranging the second digital twin in a sandbox for which a predetermined time axis has been set, and realizing a function of an entity indicated by the second digital twin in the sandbox in accordance with the time axis.

Abstract: A time feature value calculation apparatus according to an embodiment includes an interpolation unit (182) and a time feature value calculation unit (183). In accordance with a variability tendency of a biological signal exhibited in time-series data of the biological signal resulting from an abnormality value process performed to eliminate an abnormality value from the biological signal in response to an input of the biological signal having periodicity, the interpolation unit interpolates a missing value in the biological signal in the time-series data of the biological signal resulting from the abnormality value process. The time feature value calculation unit calculates a time feature value focusing on the variability tendency of the biological signal measured over an arbitrary time period, from the interpolated time-series data of the biological signal.
