`shrinkage::CrossValidationError`

Shrinkage for Rust · rust · 0.3.0

Source: src/cross_validation/error.rs

pub enum CrossValidationError<E = std::convert::Infallible>

Validation or fitting failure with the fold and candidate when available.

Errors return no partial cross-validation result. A nonconverged fit is an error, so an incomplete candidate cannot silently influence selection.

Variants

`Fold`

Source: src/cross_validation/error.rs

Fold { fold: usize, source: shrinkage::FitError<E> }

Training, path fitting, or prediction failed in a validation fold.

`fold`

Source: src/cross_validation/error.rs

fold: usize

Zero-based held-out fold identifier.

`source`

Source: src/cross_validation/error.rs

source: shrinkage::FitError<E>

Original validation, backend, or numerical failure.

`InvalidInput`

Source: src/cross_validation/error.rs

InvalidInput { source: shrinkage::FitError<E> }

Invalid configuration, folds, or full response.

`source`

Source: src/cross_validation/error.rs

source: shrinkage::FitError<E>

Underlying validation failure.

`NonConverged`

Source: src/cross_validation/error.rs

NonConverged { fold: Option<usize>, candidate: usize }

A path point did not meet its solver's convergence criterion.

`candidate`

Source: src/cross_validation/error.rs

candidate: usize

Zero-based candidate position in path order.

`fold`

Source: src/cross_validation/error.rs

fold: Option<usize>

Held-out fold, or None for the full-data refit path.

`Refit`

Source: src/cross_validation/error.rs

Refit { source: shrinkage::FitError<E> }

Fitting the full-data path failed after selection.

`source`

Source: src/cross_validation/error.rs

source: shrinkage::FitError<E>

Original fitting failure.
