WebLossless dimensionality reduction is the removal of dimensions in which there is no variance in the data. In this case, the data fall on a lower dimensional hyperplane of the n-dimensional space. In the case of 2D space, a lower-dimensional hyperplane would be a 1D line. In the current example our data do not fall perfectly onto a 1D line. redhead winter bootsWeb31 jul. 2024 · How to split/reduce dimension of a variable.
