In the training process of deep learning, optimization algorithms play a crucial role. They determine how the model parameters are updated according to the gradient of the loss function, thus affecting the model’s convergence speed and final performance. This article will introduce in depth several of the most commonly used and basic optimization algorithms: SGD, RMSProp, AdaGrad and Adam, and analyze their formulas, advantages and disadvantages.

If you also want to start your own blog and hope to:

  • The source code is placed in a warehouse so that you can write it slowly
  • The final website is automatically deployed to yourusername.github.io
  • Try to avoid the pitfalls of GitHub Pages and Hugo as much as possible

Then this process will be easier.

I am using two warehouses here:

  • Private warehouse: blogsource
  • Public warehouse: yourusername.github.io

Among them, it is best to use yourusername.github.io directly as the name of the public warehouse. If it is your first time to use GitHub Pages, it is recommended to follow this step, which is the easiest.
