Abstract: A feature-quantity extracting apparatus is provided, which can calculate a proper feature quantity, by performing a simple calculating operation. The apparatus is provided with a code-string acquiring unit for acquiring code strings for every given period from a series of input data, wherein the code string is an arrangement of codes and the code is given to a value of each piece of input data, a code-string pattern frequency counting unit for counting the number of code-string patterns for every code-string pattern among the code strings acquired by the code-string acquiring unit, wherein the code-string pattern represents a code-string whose codes are arranged in accordance with a given order, and a feature-quantity outputting unit for outputting the number of code-string patterns for every code-string pattern counted by the code-string pattern frequency counting unit as a feature quantity of the series of input data.

Abstract translation: 通过执行简单的计算操作，提供能够计算适当特征量的特征量提取装置。 该装置设置有代码串获取单元，用于从一系列输入数据中获取每个给定周期的代码串，其中代码串是代码的排列，并且代码被赋予每个输入数据的值， 代码串图案频率计数单元，用于对由代码串获取单元获取的代码串中的每个代码串模式的代码串模式的数量进行计数，其中代码串模式表示代码串的代码串 按照给定的顺序排列的特征量输出单元，用于输出由码串图案频率计数单元计数的每个码串图案的码串图案的数量作为一系列输入数据的特征量 。
