Field Documentation

int SprTreeTreeNode::question_nr

number of the question asked in the node, corresponding to the question set (-1 for a question about the node number, see first_node)

int SprTreeTreeNode::context_nr

context to which the question refers (...,-1,0,1,...)

int SprTreeTreeNode::first_node

for a question about the node number in the HMM (0,1,2,...): answer is yes if the node number is in the range [first_node,last_node]

int SprTreeTreeNode::last_node

see first_node

double SprTreeTreeNode::overlap

measure of the effect of the question (goodness of split): overlap of yes- and no-subtrees, or log likelihood change through splitting

int SprTreeTreeNode::count

occupancy (number of frames) in this subtree

int SprTreeTreeNode::statenr

for leaves in the tree: corresponding number of the tied state in the HMM

struct spr_t_tree_node* SprTreeTreeNode::yes_subtree

subtree for answer yes

struct spr_t_tree_node* SprTreeTreeNode::no_subtree

subtree for answer no
