WebSep 1, 2013 · Chirplet transform (CT) is effective in characterization of instantaneous frequency (IF) for monocomponent linear-frequency-modulated signal. However, the CT is not suitable to analyze multicomponent signal with nonlinear-frequency-modulated component. In this paper, a time–frequency fusion technique based on polynomial CT … WebMar 14, 2024 · Here's an example of how to use `PolynomialFeatures` from scikit-learn to create polynomial features and then transform a test dataset with the same features: ``` import pandas as pd from sklearn.preprocessing import PolynomialFeatures # Create a toy test dataset with 3 numerical features test_data = pd.DataFrame({ 'feature1': [1, 2, 3], …
