# XGBoost (MS\_XGBOOST)

XGBoost (Extreme Gradient Boosting) is a machine learning algorithm used for both classification and regression tasks. It is based on the gradient boosting technique, which iteratively trains weak models (usually decision trees) on the residuals of the previous models.

XGBoost optimizes a regularized objective function by minimizing the sum of the loss function and a penalty term that encourages simpler models and reduces overfitting. It also includes several advanced features, such as weighted quantile sketch for handling sparse data and cache-aware computing for faster training.

## Sample Request

Build an XGBoost model named, *"XGBoost"*

```javascript
{
    "project_id": 1,
    "parent_id": 7,
    "block_id": 8,
    "function_code": "MS_XGBOOST",
    "args": {
        "model_name": "XGBoost"
    }
}
```
