MNIST libtorch practical exercise
Ready to work
First download the MNIST database, http://yann.lecun.com/exdb/mnist/
After downloading, do not decompress it with software such as winrar. For example, t10k-images-idx3-ubyte is decompressed into t10k-images.idx3-ubyte. It is best to decompress it with tar in Linux environment.
Suppose you unzip t ...

1, Basic process of logistic regression
1. Logistic regression
Learn the law from multiple eigenvalues of a group of samples, establish a model (the learning model is abstracted as a formula f(x)), and use this model to predict the results of other samples. Logistic regression is to classify the prediction results.
Logistic regression steps:

Kaggle Titanic Survival Prediction Challenge
This is the Prediction Competition of Getting Started on kaggle. It is also a relatively entry-level and simple rookie competition. My best score seems to be in the top 8%. Taking advantage of this learning activity of Datawhale, I used the content of the data for the data analysis of the competi ...
Before learning this course, I heard the name of YOLO. During the epidemic, an up master trained the detection of pedestrian masks through yolo and it was a great success. Without further ado, let's start learning.
Basic Concepts in Object Detection
Before starting to learn YOLO, first learn some basic concepts of target detection. After all, Y ...
