Struct RealtimeAdaptationController 

pub struct RealtimeAdaptationController<T>
where
    T: Float + Debug + Send + Sync + 'static,
{ /* private fields */ }

Online controller that adapts the learning rate and momentum in response to drift detected on the loss and gradient-norm streams.

Implementations

impl<T> RealtimeAdaptationController<T>

where T: Float + Debug + Send + Sync + 'static,

pub fn new(config: RealtimeAdaptationConfig<T>) -> Result<Self>

Build a controller from a configuration.

Errors

Returns OptimError::InvalidConfig if RealtimeAdaptationConfig::validate fails.

pub fn learning_rate(&self) -> T

Current learning rate.

pub fn momentum(&self) -> T

Current momentum.

pub fn step_count(&self) -> usize

Number of observations processed so far.

pub fn cooldown_remaining(&self) -> usize

Steps remaining in the current cooldown window (zero when not cooling).

pub fn loss_detector(&self) -> &DriftDetector<T>

Immutable access to the loss-stream detector.

pub fn grad_detector(&self) -> &DriftDetector<T>

Immutable access to the gradient-norm-stream detector.

pub fn observe(&mut self, loss: T, grad_norm: T) -> AdaptationDecision<T>

Process one (loss, grad_norm) observation and adapt the hyperparameters.

The two detectors are always updated (so their internal statistics stay current even during cooldown), but at most one learning-rate adjustment is applied per call, and none while a cooldown window is active.

pub fn apply_to(&self, optimizer: &mut dyn AdvancedOptimizer<T>)

Push the controller’s current learning rate onto an AdvancedOptimizer, a thin bridge for wiring the controller into a training loop.

pub fn reset(&mut self)

Reset the controller and both detectors to their initial state.

Trait Implementations

impl<T> Clone for RealtimeAdaptationController<T>

where T: Float + Debug + Send + Sync + 'static + Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for RealtimeAdaptationController<T>

where T: Float + Debug + Send + Sync + 'static + Debug,

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

Formats the value using the given formatter.
