This disclosure relates to the field of artificial intelligence technology, and provides a method, model acquisition method, apparatus, and device for recognizing synthetic lip-sync faces. The method includes: detecting facial feature points in a sample image to obtain first facial feature data; inputting the first facial feature data and audio feature data to be synthesized into a pre-trained speech-to-lip synthesis model, and determining second facial feature data based on the output of the speech-to-lip synthesis model; training a classification model based on the first and second facial feature data to obtain a synthetic lip-sync face recognition model; inputting an image to be recognized into the synthetic lip-sync face recognition model, and determining whether the image to be recognized is a synthetic lip-sync face image based on the output of the synthetic lip-sync face recognition model. This technical solution can effectively identify synthetic lip-sync faces in images or videos, thereby reducing the probability of rumors, fraud, and other behaviors caused by synthetic lip-sync faces.

The application relates to the technical field of wireless communication networks, and discloses a transmission method for a dynamic access node, which comprises the following steps: acquiring a characteristic parameter representing the motion state of the dynamic access node and a configuration parameter of a wireless communication link; mapping the characteristic parameter to the symbol boundary of a protocol frame by using a symbol period and a sampling interval determined by the configuration parameter, so as to determine an interference evaluation window in the protocol domain; analyzing the multipath energy distribution characteristics in the interference evaluation window, combining a phase deflection trajectory determined by the characteristic parameter, and calculating a phase deflection gradient reflecting the instability trend of the radio frequency link; and implementing targeted pre-compensation for transmission parameters according to the phase deflection gradient. The application uses prior information of physical motion to offset the phase distortion caused by displacement, solves the inherent lag problem of the measurement feedback mechanism, suppresses the modulation influence of mechanical disturbance on the radio frequency local oscillator source, and ensures the signal transmission purity and demodulation reliability under complex working conditions.

The utility model provides a multi-interface wiring terminal with a protection function, which relates to the technical field of wiring terminals and comprises a base, a placement seat fixedly mounted at the top of the base, a knurling shaft arranged inside the placement seat, a rotating seat arranged on the outer wall of the knurling shaft, a torsion spring arranged on the outer wall of the knurling shaft, one end of the torsion spring fixedly connected with the rotating seat, and the other end of the torsion spring fixedly connected with the rotating seat. An anti-electric-shock rotating cover is fixedly installed on the outer wall of the rotating base, a plurality of separation openings are formed in the two sides of the interior of the anti-electric-shock rotating cover in a penetrating mode, arc-shaped plates are arranged at the two ends of the anti-electric-shock rotating cover, and a connecting base is fixedly installed on the outer wall of the anti-electric-shock rotating cover. In use, a worker presses the arc-shaped plate, and the arc-shaped plate is detached from the anti-electric-shock rotary cover through the separation port, so that a cable can be inserted into the anti-electric-shock rotary cover for connection, and the anti-electric-shock rotary cover can play a protection role to prevent the worker from touching the metal part of the cable by mistake; and external dust is prevented from being adsorbed on the metal part of the cable.
