Struct burn::nn::transformer::TransformerDecoderConfig

pub struct TransformerDecoderConfig {
    pub d_model: usize,
    pub d_ff: usize,
    pub n_heads: usize,
    pub n_layers: usize,
    pub dropout: f64,
    pub norm_first: bool,
    pub quiet_softmax: bool,
    pub initializer: Initializer,
}

Configuration to create a Transformer Decoder layer using the init function.

Fields

d_model: usize

The size of the model.

d_ff: usize

The size of the position-wise feed-forward network.

n_heads: usize

The number of attention heads.

n_layers: usize

The number of layers.

dropout: f64

The dropout rate. Default: 0.1

norm_first: bool

Layer norm will be applied first instead of after the other modules.

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
