The FFT is based on decomposition and breaking the transform into smaller transforms and combining them to get the total transform. FFT reduces the computation time required to compute a discrete Fourier transform and improves the performance by a fa

The project is to determine how much a particular factor influences on the helpfulness of a review. We extracted features like polarity, rating, average word length, helpfulness ratio the collected amazon data. We used gradient boosting classifie
