Abstract: A server receives video data from a moving body. A traveling speed control apparatus controls a traveling speed of the moving body. A quality monitoring unit monitors video quality of the video data received by the server. A speed upper limit calculation unit calculates, by using the video quality and a monitoring required condition of the video data, a maximum value of a traveling speed satisfying the monitoring required condition as an upper limit value of a traveling speed of the moving body. A speed control unit controls a traveling speed of the moving body to be equal to or lower than the calculated upper limit value.

Abstract: A first distribution estimating device determines a first probability distribution of quantized values in a predetermined value range corresponding to an input value, by using a first machine learning model. A first sampling device samples the quantized values and determines a first sample value, using the first probability distribution. A second distribution estimating device determines a second probability distribution corresponding to the first sample value, by using a second machine learning model. A second sampling device samples the quantized values in the value range and determines a second sample value, using the second probability distribution. It can be implemented in the form of any of an information processing system, an encoding device, a decoding device, a model learning device, an information processing method, an encoding method, a decoding method, a model learning method, and a program storage medium.
