This paper introduces the development and advantages of power line communication, studies and analyzes the characteristics of low-voltage power line channel and its model, and studies the system composition and principle of surface wave. A power line model was designed to realize broadband power line...

LightGBM algorithm is used to build an effective credit score prediction model for mobile users and improve the prediction system of personal credit score. Firstly, linear correlation is analyzed to build feature set, then k-means algorithm is used to analyze feature set clustering, and finally, credit...

A broadband transition device based on substrate integrated waveguide structureis proposed in this letter. With the novel guide wave structure, electromagnetic waves could be limited in the rectangular cavity formed by two rows of metal hole and the upper and lower metal border to achieve low losseffect....

The general object detection methods include one-stage and two-stage object detection algorithm. The two-stage approach, such as R-CNN family, is composed by the RPN network and object classification network with a better accuracy. The one-stage object detection algorithm represented by YOLO and CornerNet,...

This paper adopt image recognition to realize the defect detection of small probability defect parts in cluster mode. In this mode, parts with small probability of defects were identified one by one to be recognized. Different lighting conditions were tried to determine what kind of lighting should be...

In order to improve the accuracy of the classification and classification of the finger knuckle print, a method based on the improved Canny operator for the edge detection of the Finger Knuckle Print image is proposed. Firstly, the region of interest (ROI) of the Finger Knuckle Print is positioned. Secondly,...

Computer-assisted diagnosis is of significance in the timely treatment of lung cancer with classifying benign and malignant pulmonary nodules. Aiming at improving the low accuracy rate of benign and malignant pulmonary nodules and reducing the misdiagnosis rate and wrong-diagnosis rate in computer-aided...
