Computes the PCA using a sketch-based algorithm.
Computes the PCA using a sketch-based algorithm.
A sample of features to be reduced. Often O(1e6). Logically row-major.
A PCA Matrix which will perform dimensionality reduction when applied to a data matrix.
Constructs a pipeline that fits this estimator to training data, then applies the resultant transformer to the Pipeline input.
