Pattern adaptation system using tree scheme |
摘要 |
<p>Pattern matching means (3) matches categories of a reference pattern stored in reference pattern memory means (2) and input samples of an input pattern produced by input pattern generating means (1). Data statistics estimating means (6) calculates the numbers of input samples in individual nodes of a tree scheme reference pattern stored in the tree scheme reference pattern memory means (4). Node selecting means (76) selects nodes used for adaptation according to the input sample numbers calculated by the data statistics estimating means (5). Adaptation parameter generating means (7) calculates an adaptation parameter in the Nodes selected by the node selecting means (6). Reference pattern generating means (8) produces an adapted reference pattern using the calculated adaptation parameter. <IMAGE></p> |
