1. There’s several parameters we can use when defining a XGBoost classifier or regressor. If you want to see them all, check the official documentation here. In this article, we will cover just the most common ones. Such as: 1. learning_rate: The learning rate. In each boosting step, this values shrinks the weight of new features, preventing overfitting or a local minimum. This value must be between 0 and 1. The default value is 0.3. 2. max_depth: The maximum depth of a tree. Be careful, greater the depth, greater the complexity of the model and more easy to overfit. This value must be an integer greater than 0 and have 6 as default. 3. n_estimators: The number of trees in our ensemble. 4. gamma: A regularization term and it’s related to the complexity of the model. It’s the minimum loss necessary to occur a split in a leaf. It can be any value greater than zero and has a default value of 0. 5. colsample_bytree: Represents the fraction of columns to be subsampled. It’s related to the s...
