Enum OptimizerKind 

pub enum OptimizerKind {
    Sgd,
    Momentum,
    Adam,
    RmsProp,
    Adagrad,
}

The optimizer families the zero-shot selector can recommend.

Variants

Sgd

Plain stochastic gradient descent.

Momentum

SGD with classical (heavy-ball) momentum.

Adam

Adam (adaptive moments with bias correction).

RmsProp

RMSProp (root-mean-square propagation).

Adagrad

Adagrad (per-parameter accumulated-gradient scaling).

Implementations

impl OptimizerKind

pub fn all() -> [OptimizerKind; 5]

All optimizer kinds in canonical (class-index) order.

pub fn index(self) -> usize

Class index in 0..NUM_CLASSES used by the meta-model.

pub fn from_index(index: usize) -> Result<OptimizerKind>

Inverse of OptimizerKind::index; errors on an out-of-range index.

pub fn name(self) -> &'static str

Stable human-readable name.

pub fn default_hyperparameters(self) -> OptimizerHyperparameters

Canonical hyper-parameters for this optimizer family.

The learning rate is predicted separately by the regressor; these momentum / beta / epsilon values are the well-established defaults for the selected family.
