Boundary is very important for location problem. Borderalign, the core idea of borderdet, is ingenious and effective. It not only integrates boundary features into target location prediction, but also can be easily integrated into various target detection algorithms, which brings great performance improvement. In the open source implementation, the efficient CUDA implementation of borderalign will […]

By Dorian LazarCompile | VKSource: toward Data Science Perceptron is a component of artificial neural network, which is a simplified model of biological neurons in the brain. Perceptron is the simplest neural network, which consists of only one neuron. The perceptron algorithm was invented by Frank Rosenblatt in 1958. Here is a picture of a […]

By prateek JoshiCompile | VKSource | analytics vidhya introduce Machine learning frameworks or libraries sometimes change the landscape of the field. Today, Facebook has open source such a framework, Detr (detection transformer) In this paper, we will quickly understand the concept of target detection, and then directly study Detr and its benefits. object detection In […]

How can front-end programmers learn algorithms well? At present, the excellent video of algorithm is concentrated in C + +, Java and python. I have mastered the basic idea of the algorithm through watching the video of C + + for several months. All of them are translated into front-end code and written one by […]

Transport layer Perspective There are two major protocols in the transport layer: TCP and UDP. TCP is a reliable streaming protocol and UDP is an unreliable datagram protocol. However, the reliability here is limited to the end-to-end communication. When using TCP protocol, the data sent by the sender when calling the write function through the […]
