Summary:To exclude an unrealistic On-Off pattern and determine the On-Off pattern used for a machine learning.SOLUTION: In an On-Off pattern determination device, an arbitrary number of an On symbol having an arbitrary time length and an arbitrary number of an Off symbol having the arbitrary time length determine a normalization On-Off pattern of an input signal formed by being arranged in an arbitrary order to a time direction. The On-Off pattern determination device comprises: a division part; and a normalization part. The division part divides the symbol time in each symbol time length of the On symbol and the Off symbol contained in the input signal with a predetermined first time length. The normalization part sets a number sequency obtained by arranging each normalization index determined on the basis of a quotient derived from the division part in accordance with an arrangement order in the time direction of the correspondence symbol to the normalization On-Off pattern.SELECTED DRAWING: Figure 1 【課題】 機械学習のために使用されるOn−Offパターンを、非現実的なOn−Offパターンを排除して決定すること。【解決手段】 実施形態によれば、任意の時間長を有する任意の数のOnシンボルと、任意の時間長を有する任意の数のOffシンボルとが、時間方向に任意の順序で配置されてなる受信信号の、正規化されたOn−Offパターンを決定するOn−Offパターン決定装置は、除算部と正規化部とを備えている。除算部は、受信信号に含まれるOnシンボルおよびOffシンボルそれぞれのシンボル時間長を、予め決定された第1の時間長で除する。正規化部は、除算部によって得られた商に基づいて決定される正規化インデクスのおのおのを、対応するシンボルの時間方向における配置順序に従って配置して得られる数列を、正規化されたOn−Offパターンとする。【選択図】図1
