Struct MultiHeadAttentionConfig

pub struct MultiHeadAttentionConfig {
    pub d_model: usize,
    pub n_heads: usize,
    pub dropout: f64,
    pub min_float: f64,
    pub quiet_softmax: bool,
    pub initializer: Initializer,
}

Configuration to create a Multi Head Attention layer using the init function.

Fields

d_model: usize

The size of each linear layer.

n_heads: usize

The number of heads.

dropout: f64

The dropout rate. Default: 0.1

min_float: f64

The minimum value a float can take. Default: -1.0e4 This is used to mask attention scores before calculating attention weights. A value too low might result in NaN.

quiet_softmax: bool

Use “quiet softmax” instead of regular softmax.

• Usage may improve performance by allowing attention heads to deposit no information (if the sequence contains no information relevant to that head).
• Usage may reduce the entropy of weights in the model, enhancing quantization and compression.

initializer: Initializer

The type of function used to initialize neural network parameters
