Abstract: An optical computing apparatus includes: an operation module, configured to modulate a first group of optical signals based on N first electric signals to output a second group of optical signals, modulate a third group of optical signals based on N second electric signals to output a fourth group of optical signals, and adjust delays and phases of the second group of optical signals and the fourth group of optical signals; and a beam combining module, configured to combine an adjusted second group of optical signals and an adjusted fourth group of optical signals to output a fifth group of optical signals, where the fifth group of optical signals indicates a multiply-add operation result of input data and a first weight matrix and a second weight matrix.

Abstract: Various indirect feedback tuning apparatuses and methods for tuning photonic systems are enabled. For instance, a system can perform operations, such as: determining a temperature of an optical device, determining, based on the temperature of the optical device and a feedback model, a tuning input to stabilize an optical signal, and performing, based on the tuning input, feedback tuning, wherein the feedback tuning comprises thermal tuning and electrical tuning.

Abstract: The present disclosure describes methods, systems, and devices adjusting multimedia playing progress. In one implementation, a method includes playing, by a terminal, a multimedia file; receiving, by the terminal, a user input indicating a fast-forward operation that is for a playing progress of the multimedia file and that is input by a user; obtaining, by the terminal, a fast-forward record of the multimedia file; and automatically adjusting, by the terminal, the playing progress of the multimedia file according to the fast-forward record.

Abstract: Example image display methods and apparatus are described. One example method includes generating a first image based on first user operation information. The first image is stored into a memory. When second user operation information is detected, the first image corresponding to the second user operation information is determined in the memory and based on the detected second user operation information. Both the first user operation information and the second user operation information are used for displaying the first image. The first image is displayed.

Abstract: This application provides an image display method and apparatus. The method includes: generating and displaying a first image based on first user operation information; storing the first image into a memory; when detecting second user operation information, determining, in the memory and based on the second user operation information, the first image corresponding to the second user operation information, where both the first user operation information and the second user operation information are used for displaying the first image; and displaying the first image. An image displayed for the first time is cached, so that when same user operation information triggers the image to be displayed again, a terminal device may directly capture, from a cache unit, an image that needs to be displayed, and does not need to draw the image before displaying the image.
