  • Publication number: 20220121936
    Abstract: A neural network model processing method includes obtaining a first low-bit neural network model through training, where the model includes a first operation layer and a second operation layer. Each operation layer includes at least one operation. Values/a value of a parameter and/or data used for the operation are/is represented by using N bits, and N is a positive integer less than 8. The neural network model processing method further includes compressing the model to obtain a second low-bit neural network model, where the compressed model includes a third operation layer. The third operation layer is equivalent to the first operation layer and the second operation layer, and an operation layer other than the third operation layer in the at least one operation layer is the same as an operation layer other than the first operation layer and the second operation layer in the at least two operation layers.

  • Patent number: 11258271
    Abstract: A voltage error signal is provided to a PWM controller of a voltage regular and used to produce a PWM signal that drives a power stage of the regulator. When operating in an adapter current limit regulation mode, an adapter current sense voltage, indicative of an adapter current, is compared to an adapter current reference voltage to produce an adapter current error signal. A compensator receives the adapter current error signal and outputs a compensated adapter current error signal. The adapter current sense voltage, or a high pass filtered version thereof, is subtracted from the compensated adapter current error signal to produce the voltage error signal provided to the PWM controller. Alternatively, an input voltage, or a high pass filtered version thereof, is added to the compensated adapter current error signal to produce the voltage error signal.

  • Publication number: 20220039717
    Abstract: The attention recognition embodied by the method for evaluating the concentration ability of a sensory assessor is organically combined with evaluations for three categories of ranking capability, namely, excellent, good, and poor. Therefore, sensory assessors displaying high sensibility and poor attention form part of the group possessing excellent ranking capability, while sensory assessors exhibiting moderate sensibility and high attention can be found in the group possessing good ranking capability. Furthermore, sensory assessors displaying fair sensibility and high attention can be found in the group with poor ranking capability. This system can identify the concentration ability of assessors, therefore, providing support for the reliability of ranking results.

  • Publication number: 20220003633
    Abstract: The disclosure provides a device for detecting a wavefront error by modal-based optimization phase retrieval using an extended Nijboer-Zernike (ENZ) theory. The detection device includes a point light source (1), a half mirror (2), a lens (3) to be tested, a plane mirror (4) and an image sensor (5). The wavefront error of the component under test is characterized by using a Zernike polynomial, and a Zernike polynomial coefficient is solved based on an ENZ diffraction theory. The present disclosure realizes the one-time full-aperture measurement on the wavefront error of a large-aperture optical component, and can use a partially overexposed image to achieve accurate wavefront error retrieval. Meanwhile, the present disclosure overcomes the contradiction between underexposure and high signal-to-noise ratio (SNR) caused by a limited dynamic range when the image sensor (5) acquires an image. The detection device is simple and does not have high requirements for the experimental environment.
