Constructor & Destructor Documentation

LayerNormConfig() [1/2]

Mila::Dnn::LayerNormConfig::LayerNormConfig ( shape_t shape )

inlineexplicit

Construct in shape mode.

Normalizes over the trailing dimensions described by shape.

Parameters

shape

Trailing dimensions to normalize over (e.g. shape_t{ model_dim }).

LayerNormConfig() [2/2]

Mila::Dnn::LayerNormConfig::LayerNormConfig ( int64_t axis )

inlineexplicit

Construct in axis mode.

Normalizes over a single axis.

Parameters

axis	Axis along which to normalize (negative indexing supported).

Member Function Documentation

fromMetadata()

void Mila::Dnn::LayerNormConfig::fromMetadata ( const SerializationMetadata & meta )

inlineoverridevirtual

Populate configuration from provided metadata.

Implementations should read available keys and leave missing keys at their current/default values to preserve forward/backward compatibility.

Parameters

meta	Metadata to read configuration values from.

Implements Mila::Dnn::ComponentConfig.

toMetadata()

SerializationMetadata Mila::Dnn::LayerNormConfig::toMetadata ( ) const

inlineoverridevirtual

Convert configuration into a SerializationMetadata object.

Implementations should include any fields required to fully reconstruct the configuration via fromMetadata.

Returns

SerializationMetadata Metadata representation of the config.

Implements Mila::Dnn::ComponentConfig.

toString()

std::string Mila::Dnn::LayerNormConfig::toString ( ) const

inlineoverridevirtual

Produce a short, human-readable summary of the configuration.

Implementations should return a compact, single-line description suitable for logging and debugging.

Returns

std::string Human-readable summary of the configuration.

Implements Mila::Dnn::ComponentConfig.

validate()

void Mila::Dnn::LayerNormConfig::validate ( ) const

inlineoverridevirtual

Validate configuration parameters.

Called by callers to ensure the configuration represents a valid, constructible component. Implementations must throw std::invalid_argument (or a derived exception) when validation fails.

Exceptions

std::invalid_argument

If the configuration is invalid.

Implements Mila::Dnn::ComponentConfig.

withBias()

template<typename Self>

decltype(auto) Mila::Dnn::LayerNormConfig::withBias ( this Self && self, bool has_bias )

inline

Enable or disable learnable bias.

Default: true.

withEpsilon()

template<typename Self>

decltype(auto) Mila::Dnn::LayerNormConfig::withEpsilon ( this Self && self, float epsilon )

inline

Set epsilon for numerical stability.

Default: 1e-5f.
