Abstract

An information processing device including a target person information acquisition unit configured to acquire target person information about a target person, an exercise evaluation information acquisition unit configured to acquire exercise evaluation information indicating evaluation of an exercise of the target person, a storage unit configured to store a trained model that outputs instruction content in which, when the target person information and the exercise evaluation information are input, evaluation of exercise information of the target person is estimated to be improved, and a report output unit configured to input the target person information and the exercise evaluation information to the trained model and output an instruction report including the instruction content output from the trained model.

Claims (13)

1 . A coal analysis method comprising:

acquiring a surface image of a coal sample;

identifying a microstructural component group included in the surface image;

calculating a ratio of at least one of microstructural component groups;

calculating a total inert amount that is a ratio of inertinite among the microstructural component groups;

calculating an average reflectance Ro of vitrinite, which is one of the microstructural component groups;

correcting the total inert amount, after the total inert amount has been calculated from the surface image, using the total inert amount and the average reflectance Ro of vitrinite; and

blending multiple types of coals to prepare mixed coal based on the corrected total inert amount.

2 . The coal analysis method according to claim 1 , further comprising identifying the microstructural component group based on a reflectance of the microstructural component group.

3 . The coal analysis method according to claim 1 , further comprising correcting the total inert amount using a multiple regression coefficient that is determined in advance, with the total inert amount and the average reflectance Ro of vitrinite as variables.

4 . A mixed coal preparation method comprising:

identifying a total inert amount of at least part of the coal using the method according to claim 1 .

5 . A coke production method comprising using the mixed coal prepared by the method according to claim 4 to obtain coke.
