WebGradient Boosting for classification. This algorithm builds an additive model in a forward stage-wise fashion; it allows for the optimization of arbitrary differentiable loss functions. In each stage n_classes_ regression trees are fit on the negative gradient of the loss function, e.g. binary or multiclass log loss. WebThe formula was adopted to gambling and stock market by Ed Thorp, et al., see: "The Kelly Criterion in Blackjack Sports Betting, and the Stock Market" [2]. This program calculates the optimal capital allocation for the provided portfolio of securities with the formula: `f_i = m_i / s_i^2`. where. f_i is the calculated leverage of the i-th ...
