Designing a High-Pass FIR Filter using the windowing method

Finite Impulse Response (FIR) filters are of great interest in digital signal processing tasks because they have a linear phase response and do not cause many distortions to the filtered signal. Furthermore, unlike an Infinite Impulse Response (IIR) filter, the FIR filter is non-recursive, i.e. it has no feedback (it uses only samples of the input signal) and, consequently, is a naturally stable filter.

NLP: TF, IDF, and Count Vectorizer (CV)

Problem with Bag of Words: A problem with the Bag of Words approach is that highly frequent words start to dominate in the document (e.g. larger score), but may not contain as much “informational content”. Also, it will give more weight to longer documents than shorter documents. TFIDF or Term Frequency-Inverse Document Frequency indicates the importance
