Abstract: An information processing device includes: a quality evaluator that evaluates the quality of a plurality of instances of first data to generate a first evaluation result and evaluates the quality of a plurality of instances of second data to generate a second evaluation result; a learner that performs machine learning, using the plurality of instances of first data, to generate a machine learning model for detecting an anomaly; a detector that compares the first evaluation result and the second evaluation result and detects a concept drift, based on a comparison result; and an anomaly estimator that applies the machine learning model to the plurality of instances of second data to estimate whether an anomaly is present in the plurality of instances of second data.

Abstract: An information processing method includes: calculating a probability density distribution of a work time that is at least part of a setup time, based on production performance data read from storage, the setup time being time taken for a setup work that is performed between lots; determining whether the work time is anormal, based on the probability density distribution; and outputting a result of the determining.

Abstract: A multicopter system according to one aspect of the present invention includes a multicopter configured to fly in a state of holding a package and a mooring device that is installed at a target position of a flight of the multicopter and includes a linear member that extends in a predetermined direction from the target position, the multicopter including a reception portion that has the shape of a recess including an opening open toward one direction and is configured to receive the linear member via the opening.
