Feature descriptors are generated from the core area of the search image. A plurality of capsule vectors are generated from different ones of a plurality of keypoints of the feature descriptors.

One or more image of the dataset having fine-grained similarity with the search image are selected based a bundled similarity score for each image of the dataset. The bundled similarity score is a summation of the similarity scores of the image.

Abstract: The system determines that an application running user equipment (UE) is requesting a throughput intensive communication over a network. The throughput intensive communication can require a predetermined downlink and uplink throughput. The system sends a first indication to the network, specifying to a base station of the network that the UE is requesting the throughput intensive communication. The base station determines whether it can provide the downlink throughput and the uplink throughput to the UE. Upon determining that the base station cannot provide the downlink or the uplink throughput to the UE, the base station sends a first message to the UE, indicating that the throughput intensive communication is of low quality. Upon receiving the first message, the UE waits for a predetermined criterion to be satisfied before attempting to engage in the throughput intensive communication, thereby reducing network traffic by eschewing sending repeated requests for the throughput intensive communication.
