Basic introduction to heap Heap is a special kind of data structure in computer science. Heap is usually an array object that can be regarded as a complete binary tree. All its elements are stored in a one-dimensional array in the order of a complete binary tree, and the value of any parent node must be less than or equal to (greater tha ...

Time complexity: the time complexity of an algorithm is a function that qualitatively describes the running time of the algorithm. This is a function representing the length of the string of the input value of the algorithm. The time complexity is usually expressed by large O sign, excluding the low-order term and first term coefficient of this ...

preface The following is the explanation of the pointer from the definition, focusing on practice, with exquisite bushi small pictures. If you also find the pointer difficult, learn it with SThree~~ My skills are not high, so the explanation is very easy to understand~~ If you have any doubts or I am wrong, you are welcome to point out!!! ...

The principle of YOLOv5 will not be described too much here. Start directly from the output head, and then design such as encoding and decoding:   1. The original output of yolov5 series is three head heads. The picture above is the picture with the input resolution of 608 * 608. If the input is changed to the pictu ...
