Abstract: Embodiments of this specification disclose a payment method, apparatus, and device. The method includes the following: A payment operation performed by a user for a target order by using a target bank card is obtained; status information of a quick payment agreement of the target bank card is obtained; when the status information indicates that the quick payment agreement of the target bank card is in an invalid state, first prompt information for prompting the user to rebind the target bank card is generated; confirmation operation information that is entered by the user based on the first prompt information and that is used to confirm rebinding of the target bank card is received; the target bank card is rebound; and a payment of the target order is completed based on the rebound target bank card.

Abstract: The method of the present disclosure includes: for a feature matrix of each channel of an image output from an intermediate layer of a neural network: determining row(s) and column(s) having same feature values at edges of the feature matrix as row(s) to be compressed and column(s) to be compressed, deleting the feature values of the row(s) to be compressed and the column(s) to be compressed, and reserving remaining feature values as reserved values; compressing the feature values of the row(s) to be compressed and the column(s) to be compressed to obtain edge value(s); and encoding the reserved values and the edge value(s), as well as a number of the row(s) to be compressed and a number of the column(s) to be compressed, and sending a result of the encoding to a decoder for restoring the feature matrix of the each channel by the decoder.

Abstract: The invention relates to an image feature transmission method, device and system, and relates to the technical field of communication. The transmission method the following steps: extracting a feature matrix of a to-be-processed image for each channel by using a machine learning model; determining one or more incidence matrix pairs according to a comparison result of the correlation degree between the feature matrixes and a first threshold value; according to the information amount, determining a representation matrix and a represented matrix in the two feature matrixes of each incidence matrix pair; determining a corresponding relation between each representation matrix and each represented matrix; and carrying out quantization processing and coding processing on each representation matrix, the corresponding relation and the maximum characteristic value and the minimum characteristic value in each represented matrix, and then transmitting to a decoding end.
