Abstract: A compilation optimization method for program source code includes: running a first executable file, and collecting a hardware cache event, where the first executable file includes an executable program and debugging information, the executable program is obtained by compiling program source code, and the debugging information includes a correspondence between the program source code and an executable instruction in the executable program; then, obtaining first configuration information based on the hardware cache event and the debugging information, where the first configuration information includes an identifier of the program source code and a quantity of cache misses corresponding to the identifier; and finally, compiling the program source code based on the first configuration information to obtain a second executable file.

Abstract: Provided in implementations of the present application are a filtering method and apparatus, and a computer storage medium; the method comprises: acquiring pixel information to be filtered; determining edge information; and inputting the sample information to be filtered and the edge information into a neural network-based filter so as to output filtered pixels, the filter being obtained by an online filtering part combined with an offline filtering part.

Abstract: Example encoding/decoding methods, communication apparatus, and systems are provided. One example encoding method includes encoding first data by using an encoding model, to obtain N pieces of encoded data, where N is an integer greater than 2. De-correlation is performed on the N pieces of encoded data to obtain N pieces of de-correlated encoded data, where a part or all of the N pieces of de-correlated encoded data may be for determining second data, the second data is for restoring third data, and the third data is the first data, or an approximation degree between the third data and the first data is greater than a specified threshold The N pieces of de-correlated encoded data are sent.
