Abstract: A method of constructing an adaptive multiply accumulate layer in a convolutional neural network, including determining an activation data map width, an activation data map height, a channel depth, a batch, a kernel width, a kernel height and a filter set number, setting a first dimension of an adaptive multiplier layer based on the activation data map width, setting a second dimension of the adaptive multiplier layer based on the channel depth, setting a third dimension of the adaptive multiplier layer based on the filter set number and constructing the adaptive multiplier layer based on the first dimension, the second dimension and the third dimension.

Abstract: Disclosed are an optical assembly and a manufacturing method therefor. The optical assembly comprises a laser component (2) and a crystal (1). The crystal (1) is disposed on the laser component (2). The laser component (2) is used to produce a laser beam. The crystal (1) is used to split the laser beam incident onto the crystal (1) so as to generate a first beam (15) and a second beam (16). The first beam (15) is used for front light emission and the second beam (16) is used for backlight monitoring. The optical assembly can split a laser beam to achieve the backlight monitoring function without adding a splitter film. It has good stability in light splitting and reduces the risk of failure in an optical device.
