Description: The Weighted Random Forest is a supervised learning model based on the ensemble technique known as ‘random forest’, but with a particularity: it uses weighted samples during the training process. This approach allows the model to assign different levels of importance to various data instances, which can be especially useful in situations where some classes are imbalanced or where certain examples are more representative than others. By weighting the samples, the model can improve its generalization ability and performance in classification and regression tasks. The main features of this model include its robustness against overfitting, its ability to handle large volumes of data, and its capability to capture complex interactions between variables. Additionally, the Weighted Random Forest benefits from the non-parametric nature of the random forest, meaning it does not assume any specific distribution of the data, allowing for greater flexibility in its application. This model has gained popularity in various fields due to its effectiveness and ease of use, becoming a valuable tool for data analysts and data scientists seeking accurate and efficient solutions to classification and regression problems.
