Lesson 4.3&4.4 basic principle and manual implementation of gradient descent random gradient descent and small batch gradient descent

Lesson 4.3 basic principle and manual implementation of gradient descent In the previous section, we have successfully constructed the loss function of logistic regression, but due to the particularity of the logistic regression model itself, we cannot adopt the calculation idea similar to SSE when constructing the loss function (at this time, ...

pytorch_geometric(pyg) reproduction T-GCN

preface The last article introduced pyg from the basic tools provided by pyg. However, we generally use the tripartite library as a building block to build a relatively large model and use it in our own data set, rather than being satisfied with the simple model and standard data set in the running demo. Therefore, this paper will reproduce T- ...

Whether to wear mask for face detection

As an undergraduate majoring in artificial intelligence, I came into contact with face detection in my freshman study. And with the help of teachers, successfully use the code to recognize and train a series of face pictures. Now I want to share the problems and training results I encountered in the process of training the model. Face Detectio ...
