C Programming Language is one of the most common programming languages, and it can be seen in many Unix systems. Many systems and programs are also developed using C.
Therefore, the C language can be said to be a programming language with absolutely no harm when it is familiar to programmers.

Today we challenged the classifiers of different data sets again. This time, CIFAR-19 is a more difficult problem than MNIST handwriting recognition. In addition to the size of the picture becoming 32×32, CIFAR-10 is no longer a pure grayscale value, but a picture with the three primary colors of RGB.

The so-called Neural Network is the model architecture we want to build for deep learning. In official PyTorch document, the first sentence clearly states:
You can use torch.nn to build a neural network.

I believe everyone who is familiar with deep learning knows the importance of automatic derivation. In here, I will make a simple record.
The neural network operation of the deep learning model includes forward propagation and backward propagation.

Recently, when developing projects that I am interested in, there is a need to choose “colors“. I wanted to build a simple color palette for the user to select the color, and then I was getting the color the user wanted.

The original plan about PyQt5 did not intend to write so many articles. Unexpectedly, in the process of learning, I would constantly find things that I needed to record.
The calendar component is a component often used in the development of GUI interfaces, and is often used to allow users to select different dates.

Sometimes, we need to execute our program regularly, it’s like crawling financial news, waking us up, and sending us emails … etc.
In Linux, we can use crontab tool to help us set up a schedule to automatically execute programs. Today, I will simply record how to set up crontab to accomplish these functions.
