Convolutional neural network UNET learning
Video portal (entrance of station B)
As an ordered container, the neural network module will be added to the calculation diagram in the order of the incoming constructor. At the same time, the ordered dictionary with the neural network module as the element can also be used as the inco ...

This blog is only used to record the learning process, avoid forgetting and facilitate future review
Convolutional neural network is good at image processing. It is inspired by human visual nervous system. CNN has two characteristics: 1. It can effectively reduce the dimension of pictures with large amount of data into small amount of ...

For convolution formula Maybe some people know, maybe some people don't know, or just know but don't understand. But whether you know the meaning of this formula or not, it doesn't affect you to realize a convolution. I won't talk about his specific mathematical meaning first, because many people speak more clearly and thoroughly than I do. Wh ...

Relevant modules of YOLOv5 mainly exist in
common. In PY
Function: down sampling
The function of Focus module is to slice the picture, which is similar to down sampling. First, change the picture to 320 × three hundred and twenty × 12, and then go through 3 × 3, the output channel 32 finally becomes 320 ...

For an input picture, the picture is a grid image, that is, the picture is divided into one grid, and each grid represents one pixel. For patch (picture block), we traverse the picture from top to bottom and from left to right according to the size of the block, and then convolute each image block.
How to convolute: (1) For the convolution of ...

Also known as, sort out your unreliable learning records.
YOLOv5 is built through yaml configuration file. First, it is in common Build a class with the same name in the PY file, and then read the corresponding operation from the configuration file. The class of the operation will be instantiated. The whole network structur ...
