  • Publication number: 20230297455
    Abstract: An information processing device is disclosed. In the information processing device, a derivation unit derives, for each of sensors, a constraint expression obtained by substituting an observation value for a term of an observation value variable in an error model. The observation value indicates the number of present objects observed by the sensors. The error model represents correspondence between: the number of present objects in an observation range represented by the observation value variable and an error term related to an assumed detection error range of the sensor, and the number of present objects in an observation range represented by a variable indicating the number of present objects in an observation unit space. A range calculation unit calculates a possible range of the number of present objects. A reliability calculation unit calculates reliability of an estimation value of the number of present objects for each of the areas.

    Abstract: An information processing apparatus according to one embodiment includes one or more hardware processors coupled to a memory. The hardware processors function as an acquisition unit, a model generation unit, and a model generation unit. The acquisition unit serves to acquire one or more patterns from among multiple patterns each representing temporal variation of first data being data to be predicted.
