Detailed Description

Configuration class for Attention module.

Note: Some configuration options are currently disabled and marked for future implementation. The base implementation provides core multi-head attention functionality with:

• Fixed causal masking (enabled by default for autoregressive models)
• Automatic scale factor (1/sqrt(head_dim))
• No dropout (to be added in future versions)
• Unified Q/K/V input (separate projections to be added in future versions)

Constructor & Destructor Documentation

MultiHeadAttentionConfig()

Mila::Dnn::MultiHeadAttentionConfig::MultiHeadAttentionConfig ( dim_t model_dim, dim_t num_heads )

inline

Constructor with required parameters.

Parameters

model_dim	The model dimension size
num_heads	The number of attention heads

Member Function Documentation

fromMetadata()

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

inlineoverridevirtual

Populate configuration from serialization metadata.

Reads available fields from the provided metadata and updates the configuration object accordingly.

Implements Mila::Dnn::ComponentConfig.

toMetadata()

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

inlineoverridevirtual

Convert configuration to serialization metadata.

Produces a SerializationMetadata object containing the configuration fields suitable for writing into an archive by the caller.

Implements Mila::Dnn::ComponentConfig.

toString()

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

inlineoverridevirtual

String representation of the configuration.

Returns

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

Implements Mila::Dnn::ComponentConfig.

validate()

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

inlineoverridevirtual

Validate configuration parameters.

Exceptions

std::invalid_argument

If validation fails

Implements Mila::Dnn::ComponentConfig.
