Member Function Documentation

◆ num_leaves()

unsigned long Digikam::RedEye::RegressionTree::num_leaves ( ) const

References leaf_values.

◆ operator()()

const std::vector< float > & Digikam::RedEye::RegressionTree::operator() ( const std::vector< float > &  feature_pixel_values,
unsigned long &  i 
) const

requires

  • All the index values in splits are less than feature_pixel_values.size()
  • leaf_values.size() is a power of 2. (i.e. we require a tree with all the levels fully filled out.
  • leaf_values.size() == splits.size()+1 (i.e. there needs to be the right number of leaves given the number of splits in the tree) ensures
    • runs through the tree and returns the vector at the leaf we end up in.
    • #i == the selected leaf node index.
