Expand description

Structural / textual features for a single candidate node.

All fields are pre-normalized to roughly [0, 1] so they can be fed directly to the network without further scaling.

Implementations§

Source§

impl NodeFeatures

Source

pub const DIM: usize = 16

Number of features per node. Kept in sync with Self::to_vec.

Source

pub fn zeros() -> Self

Zeroed features (used to pad unused candidate slots).

Source

pub fn to_vec(&self) -> Vec<f32>

Flatten to a fixed-length vector (length == Self::DIM).

Source

pub fn heuristic_content_score(&self) -> f32

A heuristic “is this the article body?” score in [0, 1], derived purely from the features. Used as a warm-start prior and as a baseline for the supervised classifier’s tests. Not learned — just a sane linear combo of Readability-style signals.
