Positioning method and apparatus, device, and storage medium

A method for controlling a deformable mirror surface shape based on a radial primary function processes samples of a neural network training set, obtains elements of the neural network training set, characterizes the complex surface shape of the deformable mirror in each sample by using a radial primary function, takes characterization parameters of the surface shape in the each sample as an input of a neural network, and trains the neural network by taking a voltage of each piezoelectric ceramic corresponding to the complex surface shape as a corresponding output of the neural network. Training times of the neural network are consistent with a number of the samples. Finally, the trained neural network is obtained to verify the training effect of the neural network. According to the characterization parameters of the required surface, the neural network is used to control the deformable mirror to generate the required surface.

Method and means for controlling deformable mirror surface shape based on radial primary function

External inter-application input field constraints that specify a configured association relationship between an input field utilized during execution by a first application and multiple input fields utilized during execution by a second application are generated in advance. In response to user input entered into the input field of the executing first application and based on the external inter-application input field constraints, context-aware input data to the multiple input fields of the concurrently-executing second application is provided during concurrent execution of the first application and the second application.

Providing context-aware input data

External constraints with respect to at least one input field of at least one application are generated. Context-aware input data is provided to at least one input field of a currently used application, based on the external constraints.
