Abstract: In order to strategically utilize a network even when a band usable for the network varies, a packet control system (1) includes: an acquisition unit (11) that acquires a packet associated with a sending timing; an enqueue unit (12) that enqueues the packet into any of a plurality of queues in accordance with the sending timing associated with the packet; and a sending unit (17) that dequeues a packet from each of the plurality of queues in accordance with a dequeue timing specified for the queue and that sends the packet to a network. The number of packets to be sent to the network by the sending unit (17) is restricted in accordance with a band usable for the network, and the sending unit (17) sends, after the sending timing associated with the packet, a packet that is not sent at the sending timing.

Abstract: A model learning device determines a first machine learning model so as to further increase a combined loss function obtained by combining: a first loss function indicating the level of change in the reliability of a second image feature in a feature region of a reconstructed image, from the reliability of a first image feature in a feature region of the original image; and a second loss function indicating the level of recognition error. In addition, the model learning device: determines, so as to further reduce the combined loss function, respective parameter sets for a second machine learning model used in the generation of compressed data, and a third machine learning model used in the generation of the reconstructed image from the compressed data; and determines a parameter set for the fourth machine learning model in common with that for the first machine learning model.

Abstract: The moving body receives data from a remote monitoring apparatus and transmits data to the remote monitoring apparatus, via the wireless communication network. A candidate route acquisition unit acquires a candidate route of the moving body to a destination. A communication quality evaluation unit evaluates communication quality of the wireless communication network at each location included in the candidate route for each direction of communication by using communication quality information for each direction of communication. A candidate route evaluation unit evaluates communication stability of the candidate route by using communication quality evaluated for each direction of communication. A route determination unit determines a movement route of the moving body among the candidate routes by using an evaluation result of the communication stability.
