Variants

FeatureExtraction

Freeze all layers except the last few

Fields

unfrozen_layers: usize

Number of layers from the end to leave unfrozen

FineTuning

Fine-tune all layers with different learning rates

Fields

backbone_lr_ratio: f64

Learning rate ratio for backbone layers

head_lr_ratio: f64

Learning rate ratio for head layers

ProgressiveUnfreezing

Progressive unfreezing during training

Fields

unfreeze_schedule: Vec<(usize, usize)>

Schedule of (epoch, layers_to_unfreeze) pairs

Fields

layer_lr_map: HashMap<String, f64>

Map of layer names to learning rate ratios

Trait Implementations

impl Clone for TransferStrategy

fn clone(&self) -> TransferStrategy

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransferStrategy

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

Formats the value using the given formatter.

impl PartialEq for TransferStrategy

fn eq(&self, other: &TransferStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
