Information on Gradient Boosting Algorithm

Key Points

• Importance of the Algorithm:

  • Gradient Boosting is an important and popular machine learning algorithm. It is used for better results and competitive performance.
  • Before implementing it, it’s important to understand the general concept of boosting.

• Introduction to Gradient Boosting:

  • The aim of boosting is to combine weak models to create a strong model.
  • Each model corrects the mistakes of the previous one.

Algorithm Process

• Initial Model:

  • The first model takes the mean of the output and uses it as a baseline.

• Gradual Improvement:

  • For subsequent models, the mistakes of the initial model are analyzed, and new models are created to correct them.
  • This process is repeated so that the next model can reduce the errors of the previous one.

• Elevation:

  • Each subsequent model is trained with the residual of the training data.
  • A learning rate is used to avoid overfitting.

Main Benefits
