What is recorded here?
Addressed training/test prediction shift by ordering examples so supporting predictions and target statistics exclude the current label, combining practical ordered boosting and categorical-feature processing.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Original2017dynamic-boosting six-person byline differs from2018NeurIPS five-person CatBoost paper; source labels Liudmila Ostroumova Prokhorenkova/Prokhorenkova retained without resolving identity variants. Unbiased refers to specified residual/statistical mechanisms and assumptions, not a universally unbiased final estimator, absence of all leakage or dominance over every dataset.
