WebMay 30, 2024 · 1 Answer. It does basicly the same. It penalizes the weights upon training depending on your choice of the LightGBM L2-regularization parameter 'lambda_l2', aiming to avoid any of the weights booming up to a level that can cause overfitting, suppressing the variance of the model. Regularization term again is simply the sum of the Frobenius norm ... WebFeb 1, 2024 · You can use squared loss for classification, you cannot use classifier for regression. $\endgroup$ ... How is gain computed in XGBoost regressor? 5. Training a binary classifier (xgboost) using probabilities instead of just 0 and 1 (versus training a multi class classifier or using regression) 3.
