What it does

Gradient boosting builds one small model after another. Each new model tries to fix the last mistakes.

Boosting: Making a model stronger • Gradient: Direction of the error

How it works

  • Start with a simple guess.
  • Check where the guess was wrong.
  • Add a new small model that focuses on those mistakes.

Uses & Applications

  • Search engines can use it to rank better results higher.
  • A store can predict which products may sell next week.
  • A delivery company can predict which packages might arrive late.
In short

It is a chain of models where each one fixes mistakes from the one before it.
