`shrinkage::SolverStep`

Shrinkage for Rust · rust · 0.3.0

Source: src/solver/observer.rs

pub struct SolverStep<'a>

A borrowed optimization state, valid only during an observer callback.

Coefficients and the intercept use the solver's optimization scale. Returned fits back-transform these parameters using their preprocessing metadata. Iteration counts use the selected solver's documented units. Inner callbacks count IRLS sweeps, Gaussian hybrid block visits, or binomial hybrid quadratic iterations. Rejected line-search trials are never emitted.

Fields

`coefficients`

Source: src/solver/observer.rs

pub coefficients: &'a [f64]

`intercept`

Source: src/solver/observer.rs

pub intercept: f64

Optimization-scale unpenalized intercept.

`iteration`

Source: src/solver/observer.rs

pub iteration: usize

Solver iteration count at this state.

`kind`

Source: src/solver/observer.rs

pub kind: StepKind

Operation that produced this state.
