“Use a toy dataset to train a classification model” is a simplest deep learning practice.
Today I want to record how to use MNIST A HANDWRITTEN DIGIT RECOGNITION dataset to build a simple classifier in PyTorch.

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.

If we want to use keyboard and mouse in our interface in PyQt5, we have to set it up. So I think recoding about these is a good idea.

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.

In fact, I haven’t used this tool for a long time. I suddenly had this need recently, so I found the code that I had studied before, and started to look for functions that I hadn’t tested before, and recorded it as a note by the way.
