LightGBM: The Fastest Option of Gradient Boosting
Learn how to implement a fast and effective Gradient Boosting model using Python
Introduction
When we talk about Gradient Boosting Models [GBM], we often also hear about Kaggle. This algorithm is very powerful, offering many tuning arguments, thus leading to very high accuracy metrics, and helping people to win competitions on that mentioned platform.
However, we are here to talk about real life. Or at least an implementation that we can apply to problems faced by companies.
Gradient Boosting is an algorithm that creates many models in sequence, always modeling on top of the error of the previous iteration and following a learning rate determined by the data scientist, until it reaches a plateau, becoming unable to improve the evaluation metric anymore.
Gradient Boosting algorithm creates sequential models trying to decrease the previous iteration’s error.
The downside of GBMs is also what makes them so effective. The sequential construction.
If each new iteration is in sequence, the algorithm must wait for the completion of one iteration before it can start another, increasing…
