Webb7 apr. 2024 · In the last issue we used a supervised learning approach to train a model to detect written digits from an image. We say it is supervised learning because the training data contained the input images and also contained the expected output or target label.. However we frequently need to use unlabeled data. When I say unlabeled data, I mean …
Webb13 maj 2024 · Implementation: SciPy’s stats package provides a function called boxcox for performing box-cox power transformation that takes in original non-normal data as input and returns fitted data along with the lambda value that was used to fit the non-normal distribution to normal distribution.
