Web6. Dataset transformations¶. scikit-learn provides a library of transformers, which may clean (see Preprocessing data), reduce (see Unsupervised dimensionality reduction), expand (see Kernel Approximation) or generate (see Feature extraction) feature representations. Like other estimators, these are represented by classes with a fit … WebThis class inherits from DatasetFolder so the same methods can be overridden to customize the dataset.. Parameters:. root (string) – Root directory path.. transform (callable, optional) – A function/transform that takes in an PIL image and returns a transformed version.E.g, transforms.RandomCrop target_transform (callable, optional) – A function/transform …
