ICA; independent component analysisの英語

A separation signal is created by processing applying independent component analysis (ICA), on an observation signal composed of the mixed signal in which outputs from a plurality of sound sources are mixed, and speech recognition processing is performed on each separation signal.例文帳に追加

Acceleration sensors 1a are arranged in many points (eight points in this case) of girders and/or floor slabs of a bridge assumed to have cracks, and the change of independent components based on an independent component analysis (ICA) is detected from sensor signals to carry out an abnormality diagnosis of the whole bridge (an upper structure).例文帳に追加

Mixed signals are subjected to separation processing, by applying independent component analysis (ICA) for observation signals, based on mixed signals of two or more sound sources obtained by a sound source separation microphone and separation signals corresponding to each sound source are generated.例文帳に追加

音源分離用マイクが取得した複数音源の混合信号に基づく観測信号に対して独立成分分析（ＩＣＡ：Ｉｎｄｅｐｅｎｄｅｎｔ Ｃｏｍｐｏｎｅｎｔ Ａｎａｌｙｓｉｓ）を適用して混合信号の分離処理を行い、各音源対応の分離信号を生成する。 - 特許庁

To solve the problem that the performance of separation of ICA (Independent Component Analysis) to separate each source signal from a reception signal in which a plurality of source signals are interfered deteriorates when the source signal is a wide band signal, or a frequency temporally fluctuates in a wide band even in the narrow band signal, because of assuming an interfered model which does not temporally fluctuate in the narrow band.例文帳に追加

複数の源信号が混信した受信信号から各源信号を分離するＩＣＡは，狭帯域で時間的に変動しない混信モデルを仮定しているので、源信号が広帯域信号や、狭帯域でも広帯域に周波数が時間変動する場合、分離性能が劣化する。 - 特許庁
