applySoftmax()

template<typename Container_t >

void MVAUtils::detail::applySoftmax

(

Container_t &

x

)

apply softmax to the input: {exp[xi] / sum(exp[xj]) for xi in x}

computeRight()

std::vector<index_t> MVAUtils::detail::computeRight ( const std::vector< int > &  vars )

inline

Compute the offsets between the nodes to their right children from a serialized representation of the tree with preoder traversal.

Returns 0 for leafs. This function is used in the constructors of the Forest* classes
