Struct TransferLearning 

pub struct TransferLearning<A: Float + Send + Sync> { /* private fields */ }

Transfer learning system: stores per-source-domain experiences and replays them into a target domain, weighted by measured domain similarity.

Implementations

impl<A: Float + Send + Sync + Clone> TransferLearning<A>

pub fn new() -> Self

Creates a transfer-learning system using instance transfer.

pub fn set_strategies( &mut self, strategies: Vec<TransferStrategy>, ) -> Result<(), String>

Requests a specific set of transfer strategies.

Returns an error naming any strategy this crate cannot carry out, rather than accepting it and silently substituting instance transfer.

pub fn strategies(&self) -> &[TransferStrategy]

Strategies currently in force.

pub fn register_source( &mut self, source_id: String, experiences: Vec<MetaExperience<A>>, characteristics: Vec<A>, )

Registers a source domain’s experiences and characteristic vector.

pub fn source_domain_count(&self) -> usize

Number of registered source domains.

pub fn metrics(&self) -> &TransferMetrics<A>

Measured transfer outcomes.

pub fn domain_similarity(&self) -> Option<A>

Similarity between the registered source and the last reported target.

pub fn select_transfer_batch( &mut self, target_characteristics: Vec<A>, limit: usize, ) -> Vec<MetaExperience<A>>

Selects source experiences to replay into a target domain described by target_characteristics.

Returns an empty vector when there is no registered source, when the domains are not similar enough (below MIN_TRANSFER_SIMILARITY), or when the similarity cannot be computed — all of which are honest “nothing to transfer” outcomes rather than errors.

pub fn record_transfer_outcome(&mut self, reward_before: A, reward_after: A)

Records the outcome of a completed transfer: the target’s reward before and after replaying the transferred experiences.

Trait Implementations

impl<A: Clone + Float + Send + Sync> Clone for TransferLearning<A>

fn clone(&self) -> TransferLearning<A>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Debug + Float + Send + Sync> Debug for TransferLearning<A>

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

Formats the value using the given formatter.

impl<A: Float + Send + Sync + Clone> Default for TransferLearning<A>

fn default() -> Self

Returns the “default value” for a type.
