1. An aerosol generating device comprising:
a storage configured to store an aerosol source;
a load configured to atomize the aerosol source by heat generated by receiving supply of electric power from an electric power source;
a fibrous or porous material configured to retain the aerosol source, which is supplied from the storage, in a state that the aerosol source can be heated by the load;
a sensor configured to output a value relating to temperature of the load; and
circuitry configured to:
perform, in response to detecting a predetermined input from a user corresponding to a request for generation of aerosol, electric power supplying cycles by supplying electric power from the electric power source to the load; and
estimate or detect at least one of a state of the storage and a state of the fibrous or porous material based at least on first values and second values, wherein
the first values are:
output values of the sensor obtained in a first electric power supplying cycle, or
values relating to behavior of the temperature of the load in the first electric power supplying cycle, the values derived from the output values obtained in the first electric power supplying cycle;
the first electric power supplying cycle is a single one of the electric power supplying cycles;
the second values are:
output values of the sensor obtained in a second electric power supplying cycle, or
values relating to behavior of the temperature of the load in the second electric power supplying cycle, the values derived from the output values obtained in the second electric power supplying cycle; and
the second electric power supplying cycle is a single one of the electric power supplying cycles occurring after the first electric power supplying cycle.
