Abstract: There are provided method, apparatus, device, and medium for determining update gradient for contrastive learning model. In the method, a gradient factor of a first type for the contrastive learning model is determined based on a first group of training data and a second group of training data for training the contrastive learning model. The gradient factor of the first type is not used for backpropagation during a training process. In a first stage of the training process, a gradient factor of a second type associated with the first group of training data is determined based on the contrastive learning model. The gradient factor of the second type is used for backpropagation during the training process. Gradient is obtained for updating the contrastive learning model based on the gradient factor of the first type and the gradient factor of the second type associated with the first group of training data.

Abstract: Provided are a data processing system and method based on dynamic redundancy heterogeneous encoding, and a device. The method comprises: respectively performing error correction encoding on information to be processed and a processing rule, so as to form encoded information to be processed and an encoded processing rule; processing, by using the encoded processing rule, the encoded information to be processed, so as to obtain response data; and then performing error correction decoding on N pieces of response data, so as to obtain processing result information of the information to be processed.

Abstract: Provided in the present application are a data processing method and apparatus based on data coding, and a device. The method comprises: performing N-channel error correction coding on data to be processed that is in information to be processed, so as to obtain N pieces of coded data to be processed; by using coded meta-channel data obtained by means of error correction coding, performing redundancy processing on the coded data to be processed, so as to obtain N pieces of response data; and then performing error correction decoding on the N pieces of response data, so as to obtain processing result information of the information to be processed.

Abstract: The present application provides an instruction encoding-based data processing method and apparatus, and a device. N-path error correction encoding is performed on an instruction in information to be processed to obtain N encoded instructions, the encoded instructions and encoded meta channel programs obtained by the error correction encoding are used to perform redundant processing on data to be processed to obtain N pieces of response data, and then error correction decoding is performed on the N pieces of response data to obtain processing result information of the information to be processed. Because the N encoded instructions are heterogeneous and the encoded meta channel programs used in the N-path processing are heterogeneous, the randomness of the processing process can be improved, generalized disturbance in the data processing process can be corrected in combination with the error correction encoding and decoding methods, and thus the security of data processing is improved.

Abstract: A method including acquiring page data after receiving an access request for a target page, the page data comprising data corresponding to a plurality of tab pages, and the plurality of tab pages comprising a first tab page and at least one second tab page, wherein the first tab page comprises links to a plurality of first application services, and the links are used to jump to render render pages of the first application services; the second tab page corresponds to a render page of a second application service; and switching to the second tab page to display the render page of the second application service by receiving a switching operation performed between the plurality of tab pages. An access to a plurality of application services is achieved more efficiently, and meanwhile, excessive impact on traffic balance among the plurality of application services is avoided.
