Linguistic Boosting Factor. Type of extensions: XfDtShowKnn (closest by dssm-model, trained to predict XfDtShow extensions). Aggregation over all extensions. Highest weighted factor value. A mixture of multiple streamlines, the weight is computed from a fixed polynomial of the component weights on a given annotation. The word weights aggregation algorithm is BclmMixPlain: a linear mixture of the annotation Bclm weight and the weighted Positionless word weight, then the word counters are aggregated via bm15. The normalization factor is 10^(-5).

description Фактор лингвистического бустинга. Тип расширений: XfDtShowKnn (ближайшие по dssm-модели, обучаемой предсказывать XfDtShow расширения). Агрегация по всем расширениям. Наибольшее взвешенное значение фактора. Смесь множества стримов, вес высчитывается по фиксированному полиному от весов компонент на данной аннотации. Алгоритм агрегации весов слов - BclmMixPlain: линейная смесь аннотационного Bclm веса и взвешенного Positionless веса слова, затем пословные счётчики агрегируются через bm15. Коэффициент нормализации 10^(-5).
