  • Publication number: 20210084664
    Abstract: The present disclosure relates to a user equipment (UE) which comprises a transmitter, which transmits a signal to a base station over a channel, wherein the signal is transmitted based on an initial channel quality information indicating a first channel quality of the channel. A receiver of the UE receives a transmission quality information indicating a second channel quality of the channel used for transmitting the signal. A processing circuitry of the UE estimates a transmission quality based on the initial channel quality information and the transmission quality information, wherein the transmission quality indicates whether the transmission of the signal over the channel was successful or not.

  • Patent number: 10671812
    Abstract: Certain aspects produce a scoring model that can automatically classify future text samples. In some examples, a processing device perform operations for producing a scoring model using active learning. The operations includes receiving existing text samples and searching a stored, pre-trained corpus defining embedding vectors for selected words, phrases, or documents to produce nearest neighbor vectors for each embedding vector. Nearest neighbor selections are identified based on distance between each nearest neighbor vector and the embedding vector for each selection to produce a text cloud. Text samples are selected from the text cloud to produce seed data that is used to train a text classifier. A scoring model can be produced based on the text classifier. The scoring model can receive a plurality of new text samples and provide a score indicative of a likelihood of being a member of a selected class.
