Abstract: This application discloses a model training method, which may be applied to the field of artificial intelligence. The method includes: when training a first neural network model based on a training sample, determining N parameters from M parameters of the first neural network model based on a capability of affecting data processing precision by each parameter; and updating the N parameters. In this application, on a premise that it is ensured that the data processing precision of the model meets a precision requirement, because only N parameters in M parameters in an updated first neural network model are updated, an amount of data transmitted from a training device to a terminal device can be reduced.

Abstract: Example optical signal processing apparatuses and methods are provided. One example apparatus includes: N light sources, a wavelength multiplexer, an optical processor, a dither application circuit, a first detection circuit, a second detection circuit, and a feedback control circuit. The light source generates a single-wavelength signal. The dither application circuit applies a dither signal to the light source. The wavelength multiplexer generates a multi-wavelength signal based on the single-wavelength signal. The first detection circuit is configured to obtain a first power signal of a signal input to the optical processor. The second detection circuit is configured to obtain a second power signal of a signal output from the optical processor. The feedback control circuit adjusts a working parameter of the optical processor based on the dither signal corresponding to the single-wavelength signal, the first power signal, and the second power signal.

Abstract: This application discloses a temperature feedback control apparatus, method. The method includes two electric switches, a feedback control unit and an optical component. A first electric switch is configured to control that only a first channel of at least two channels that correspond to the first electric switch is conducted at a moment, to feed back an optical signal of a target optical component connected to the first channel to the feedback control unit. The feedback control unit is configured to calculate temperature of the corresponding optical component based on an electrical signal converted from the optical signal, to obtain a control signal. The second electric switch is configured to control, when the first channel is conducted, that only the second channel is conducted, to transmit the control signal to the target optical component to adjust its temperature. The optical component connects to both the first and second channels.
