Feature normalization example
WebOn the second part of the example we show how Principle Component Analysis (PCA) is impacted by normalization of features. To illustrate this, we compare the principal components found using PCA on unscaled … WebWith the default arguments it uses the Euclidean norm over vectors along dimension 1 1 1 for normalization. Parameters: input – input tensor of any shape. p – the exponent value in the norm formulation. Default: 2. dim – the dimension to reduce. Default: 1. eps – small value to avoid division by zero. Default: 1e-12
