Implementations

impl PcaOutputBuffers

pub fn new( resources: &CuvsResources, rows: usize, columns: usize, n_components: usize, ) -> Result<Self>

pub fn into_transformed_columns( self, fit: PcaFitTransform, ) -> Result<Vec<Series>>

Consume the output owner and split the column-major transformed matrix into independent cudf-owned device columns.

pub fn into_transformed_dataframe( self, fit: PcaFitTransform, ) -> Result<DataFrame>

Consume the output owner and return the transformed PCA relation as a cudf DataFrame with component_0..N columns.

Trait Implementations

impl Debug for PcaOutputBuffers

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
