Title
(EN) SYSTEM AND METHOD FOR EXTRACTING REPRESENTATIVE FEATURE
(FR) SYSTÈME ET PROCÉDÉ D'EXTRACTION DE CARACTÉRISTIQUE REPRÉSENTATIVE
(JA) 代表特徴抽出システムおよび方法
Abstract
(EN)
A representative feature extraction system for selecting a representative feature from an input data group is provided with an occurrence distribution memorizing means for memorizing occurrence distributions regarding feature amounts which are assumed to be input, an evaluation value calculation means for obtaining an evaluation value of each piece of data in the data group by calculating a sum of distances to other pieces of data in the data group on the basis of the occurrence distributions, and a data selection means for selecting a piece of data having the minimum evaluation value as a representative feature of the data group.
(FR)
L'invention concerne un système d'extraction d'une caractéristique représentative, destiné à sélectionner une caractéristique représentative dans un groupe de données d'entrée, doté d'un moyen de mémorisation de la distribution des survenances destiné à mémoriser des répartitions de survenance se rapportant à des valeurs de caractéristiques dont on suppose qu'elles seront entrées, un moyen de calcul d'une valeur d'évaluation destiné à obtenir une valeur d'évaluation de chaque élément de données dans le groupe de données, en calculant une somme des distances par rapport à d'autres éléments de données dans le groupe de données sur la base des répartitions de survenance, et un moyen de sélection de données destiné à sélectionner un élément de données présentant la valeur d'évaluation la plus faible comme caractéristique représentative du groupe de données.
(JA)
入力されたデータ群から代表特徴を選択する代表特徴抽出システムは、入力が想定される特徴量についての生起分布を記憶する生起分布記憶手段と、データ群中の各データについて、生起分布に基づいて当該データ群に含まれる他のデータまでの距離の和を算出して当該データの評価値を求める評価値計算手段と、評価値が最小であるデータをデータ群の代表特徴として選択するデータ選択手段と、を備える。
