In signal processing, undersampling or bandpass sampling is a technique where one samples a bandpass-filtered signal at a sample rate below its Nyquist rate (twice the upper cutoff frequency), but is still able to reconstruct the signal. When one undersamples a bandpass signal, the samples are indistinguishable from the samples of a low-frequency alias of the high-frequency signal. Such sampling is also known as bandpass sampling, harmonic sampling, IF sampling, and direct IF-to-digital conversion. (Wikipedia).

Machine Learning with Imbalanced Data -Part 4 (Undersampling, Clustering-Based Prototype Generation)
In this video, we discuss under-sampling techniques for learning from imbalanced data sets, including random sampling and clustering-based prototype generation. We also see how to implement these techniques using NumPy, Scikit-learn, and Imbalanced-learn in Python. We notice that the proto

Machine Learning with Imbalanced Data - Part 5 (Ensemble learning, Bagging classifier)
In this video, we discuss the use of ensemble learning strategies to address the class imbalance problem. Therefore, one can use a combination of data-level preprocessing methods and cost-sensitive learning to improve the performance of classifiers on class-imbalanced data sets. #Imbalan
