WebbThe bias of the truncated mode depends on the value of the ntree_start parameter: 0 — the original bias value is used. Greater than 0 — the value is set to 0. Webb20 mars 2024 · sklearn CalibratedClassifierCV doesn't support strings, it's an issue in sklearn rather in catboost. To overcome the problem you can enumerate all the string values and use integer values instead of strings.
