Xf One Se Knn All Max W F Max W Field Set1 Bm15 F Log K0001

Linguistic Boosting Factor. Type of extensions: XfOneSeKnn (closest by dssm-model, trained to predict XfDtShow extensions). Aggregation over all extensions. Highest weighted factor value. Normalized to the maximum weight of the extension. Weighted aggregation of stream Url,Title,Body,Links,CorrectedCtr,LongClick,OneClick,BrowserPageRank,SplitDwellTime,SamplePeriodDayFrc,SimpleClick,YabarVisits,YabarTime. Word weights aggregation algorithm: Bm15FLog (Bm15 aggregation of word occurrence logarithms). The normalization coefficient is 0.001.
