Struct ViTBlock 

Source 
pub struct ViTBlock {
    pub config: ViTBlockConfig,
    pub weights: ViTBlockWeights,
}
Expand description

A single pre-norm ViT transformer block.

Implementations§

Source§

impl ViTBlock

Source

pub fn new(cfg: ViTBlockConfig, rng: &mut LcgRng) -> Self

Construct a new block with Xavier-initialised weights.

Source

pub fn forward(&self, tokens: &[f32], n_tokens: usize) -> VisionResult<Vec<f32>>

Forward pass.

tokens is flat [n_tokens, embed_dim]. Returns [n_tokens * embed_dim].

Pipeline:

h   = LN1(tokens)
h   = MHSA(h)  + tokens   (residual)
h2  = LN2(h)
out = MLP(h2)  + h        (residual)
