Abstract: A communication apparatus that can improve communication quality is provided. A communication apparatus including a face unit for achieving a configuration simulating right and left eyes by a mechanical movement or a display. The communication apparatus includes a detection unit configured to detect a distance to and a direction of a communication partner, and a control unit configured to control the mechanical movement or the display of the configurations in such a way that viewpoints of the right and left eyes are directed to the distance and the direction detected by the detection unit.

Abstract: In an information processing device, a determination unit determines whether a first distance from a position of a vehicle within a predetermined range of an intersection having a stop line to a road link of the intersection is shorter than a second distance from the position of the vehicle to a road link other than the road link of the intersection, based on vehicle information including information indicating the position of the vehicle and map information. An identification unit identifies whether the vehicle has stopped at the stop line, based on the vehicle information, when the first distance is determined to be shorter than the second distance.

Abstract: A catalyst deterioration detection device is provided to detect deterioration of a catalyst provided in an exhaust passage of an internal combustion engine. The catalyst deterioration detection device includes a storage device and processing circuitry. The storage device stores map data specifying a mapping that uses time series data of an excess amount variable in a first predetermined period and time series data of a downstream detection variable in a second predetermined period as inputs to output a deterioration level variable. The processing circuitry executes an acquisition process that acquires data, a deterioration level variable calculation process that calculates a deterioration level variable of the catalyst based on an output of the mapping using the data acquired by the acquisition process as an input. The map data includes data that is learned through machine learning.
