Struct Truncation 

pub struct Truncation {
    pub rel_eps: f64,
    pub gavish_donoho: bool,
    pub max_rank: usize,
}

Rank-selection rule for each unfolding in tt_svd.

Fields

rel_eps: f64

Relative Frobenius budget ε: each of the d−1 SVDs discards at most δ = ε‖X‖/√(d−1) (Oseledets 2011), so ‖X − X̂‖ ≤ ε‖X‖.

gavish_donoho: bool

Additionally cap each rank at the Gavish–Donoho optimal hard threshold ω(β)·σ_med (unknown-noise form).

max_rank: usize

Hard rank cap.
