Struct BakedMaskEncoder 

pub struct BakedMaskEncoder { /* private fields */ }

A tiny MLP whose weights are deterministically “baked” from a mask’s 64-float signature_vector.

Architecture: Linear(64→H) → ReLU → Linear(H→64)

Weight derivation (fully deterministic, no training needed):

• Each weight is seeded by BLAKE3 hash of the signature, ensuring structurally unique encoders per mask.

Memory: (64H + H + H64 + 64) * 4 bytes ≈ 66 KB for H=128

Implementations

impl BakedMaskEncoder

pub fn from_signature(signature: &[f32], hidden: usize) -> Self

Bake an encoder from a mask’s signature vector.

pub fn forward(&self, input: &[f32; 64]) -> [f32; 64]

Forward pass: x → Linear → ReLU → Linear → output

pub fn reconstruction_error(&self, features: &[f32; 64]) -> f32

Reconstruction error (MSE) between input features and reconstruction

pub fn memory_bytes(&self) -> usize

Memory usage in bytes
