  • Publication number: 20240122047
    Abstract: A display substrate includes an underlaying substrate, a display structure layer arranged on the underlaying substrate, and a light regulation layer arranged at a light exiting side of the display structure layer. The display structure layer includes multiple sub-pixels. An orthographic projection of the light regulation layer on the underlaying substrate does not overlap with opening regions of the multiple sub-pixels. The light regulation layer is configured to adjust an emergent direction of light of at least one color emitted from the display structure layer.

  • Publication number: 20240046086
    Abstract: Disclosed are a quantization method and quantization apparatus for a weight of a neural network, and a storage medium. The neural network is implemented on the basis of a crossbar-enabled analog computing-in-memory (CACIM) system, and the quantization method includes: acquiring a distribution characteristic of a weight; and determining, according to the distribution characteristic of the weight, an initial quantization parameter for quantizing the weight to reduce a quantization error in quantizing the weight. The quantization method provided by the embodiments of the present disclosure does not pre-define the quantization method used, but determines the quantization parameter used for quantizing the weight according to the distribution characteristic of the weight to reduce the quantization error, so that the effect of the neural network model is better under the same mapping overhead, and the mapping overhead is smaller under the same effect of the neural network model.
