WebMay 26, 2024 · LCE applies cascade generalization locally following a divide-and-conquer strategy — a decision tree, and reduces bias across a decision tree through the use of boosting-based predictors as base learners. The current best performing state-of-the-art boosting algorithm is adopted as base learner (XGBoost, e.g., XGB¹⁰, XGB¹¹ in Figure 2). WebSep 22, 2024 · Trying to beat random forest with xgboost. I have a small time series dataset of about 3000 samples and 5 features. With xgboost, my predictions seem biased (consistently overestimating the target). No matter how many estimators I throw at the problem along with hyperparameter tuning, I can't seem to beat a random forest.
