Fields

n_atoms: usize

max_iter: usize

top_k: usize

assignment: LinearDictionaryAssignment

temperature: f64

code_ridge: f64

tolerance: f64

center_rank_one: bool

K=1 lane only. When false (default) the rank-one lane takes the leading eigenvector of the UNCENTERED second-moment matrix XᵀX (byte-identical to historical behavior), which is only a true centered-PCA ceiling when x is already mean-centered. When true the lane subtracts the column mean, takes the leading eigenvector of the CENTERED second-moment matrix, fits the rank-1 code on the centered data, and adds the mean back — so the reported EV (measured against the crate’s centered denominator) is a genuine centered-PCA ceiling even on uncentered input. Because the reconstruction is then affine (mean + rank-1), the returned fitted INCLUDES the mean and is NOT equal to assignments.dot(atoms) in this mode.
