Abstract: This application relates to a model migration method in the field of artificial intelligence, including: obtaining sample data of a target task, where the sample data includes a plurality of image samples; separately evaluating N pre-trained models based on the sample data, to obtain N evaluation values, where the evaluation value represents adaptation between the pre-trained model and the target task, and N?2; determining K pre-trained models from the N pre-trained models based on the N evaluation values, where the K pre-trained models are models corresponding to first K evaluation values obtained by sorting the N evaluation values in descending order, and 1?K?N; and processing the sample data based on the K pre-trained models to obtain a target model used to process the target task, where the target model includes the K pre-trained models.

Abstract: Disclosed are a rocker footboard device and a vehicle. The rocker footboard device includes a mounting seat, a rotary driving device, a first connecting rod, a second connecting rod, a sliding sleeve, and a footboard, where the rotary driving device is provided with a driving shaft, the sliding sleeve is pivotally connected with the mounting seat through a second pivot shaft, and a middle segment of the second connecting rod is slidably provided on the sliding sleeve. The rotary driving device drives the first connecting rod to rotate around the driving shaft, and the first connecting rod drives the second connecting rod to slide in the sliding sleeve. As a result, the second connecting rod is extended or retracted, thereby extending or retracting the footboard. Compared with the four-rod linkage mechanism, the rocker footboard device has the simpler structure, smaller size, lower manufacturing cost, and higher production efficiency.

Abstract: The disclosure provides a method for enriching epileptiform discharges and predicting SOZ during epilepsy interictal period, including the following steps: obtaining stereotactic electroencephalogaphy signals of patient during the epilepsy interictal period; preprocessing the stereotactic electroencephalogaphy signals to obtain processed stereotactic electroencephalogaphy signals; dividing the processed stereotactic electroencephalogaphy signals into a training set and a test set, dividing the training set into a plurality of signal segments by using a sliding window, and performing a self-supervised reconstruction training on the signal segments based on a Transformer encoder model to obtain a trained Transformer encoder model; inputting the test set into the trained Transformer encoder model, obtaining reconstructed values of each of the signal segments, comparing the reconstructed values of each of the signal segments with values of the stereotactic electroencephalogaphy signals to obtain deviation values

Abstract: The current invention pertains to digital livestock breeding, focusing on a novel image acquisition system designed for assessing the health of lactating cow teats. Addressing challenges related to image capture quality and operational complexity in dairy cow teat examination, the solution comprises a guard plate, a telescopic column with a hinge mechanism, and a photo unit. Straps are positioned at each end of the guard plate, and an installation seat is located at the rotational juncture. The telescopic column includes a fixed cylinder pivotally attached to the guard plate and a movable column within it, extending beyond the fixed cylinder. Additionally, a fixed grip is mounted on one side of the fixed cylinder's outer wall. This innovation streamlines user-friendly shooting and adjustment processes while enabling timely cleaning of the lens and light-emitting device, ensuring image clarity.

Abstract: A rapid cleaning system of milking cups in milking hall is provided. The rapid cleaning system includes a bottom plate, a supporting pipe fixed on the top of the bottom plate, a supporting positioning component fixed on the top of the supporting pipe, a lifting mechanism sliding sleeved with the supporting pipe, and a clamping and fixing mechanism connected to the outer ring of the supporting pipe and the supporting positioning component. A placing platform for the milking cup group is provided, in the process of placing the milking cup group, the milking cup group is cleaned and disinfected.

Abstract: A layer of wires is preliminarily stranded by a layer of strand-through holes, and a first strand cylinder is used for the second pressing and stranding. The next layer of special-shaped single wires is stranded through a second pre-stranding assembly, and then the last layer of wires is stranded through a main stranding mold, thus stranding a plurality of layers at the same time with a compact structure. The outer circumference of the guide roller matches that of the special-shaped single wire, avoiding the reduced quality of stranded cable core. The first rotating connector is bowl-shaped and is provided with a layer of strand-through holes together with a structure in which a first pull rod is in fit with the rotating connector and a structure in which a second pull rod is in fit with the rotating connector.
