構造テンソル場理論（STFT）は何を変えるか？ #12

素人×AIが導いた構造テンソル場理論（STFT） このnoteは、物理学の専門教育を受けていない私が、AIとの対話を通じて生まれた仮説「構造テンソル場理論（STFT：Structural Tensor Field Theory）」のアイデアスケッチです。 「力」「エネルギー」「時間」など、物理 ...

STFT-like time frequency representations for nonstationary signal — From evenly sampled ...

Abstract: Spectrograms provide an effective way for time-frequency representation (TFR). Among these, short-time Fourier transform (STFT) based spectrograms are extensively used for various ...

A new time-frequency analysis based upon AR model

Abstract: In this paper we analyzed the reasons why the discrete Wigner-Ville-distribution (WVD) of real-valued signal sampled at the Nyquist rate has spectral aliasing, whereas short time Fourier ...
