Struct EmlTree 

pub struct EmlTree { /* private fields */ }

Depth-configurable EML evaluation tree.

The tree maps input_count features through layers of affine mixing and EML operators to produce a single scalar output.

Architecture

• Level 0: 2^(depth-1) affine combinations of input features (3 params each via softmax3 mixing).
• Levels 1..depth-1: EML nodes halving the width at each level, with mixing weights.
• Output: final EML node producing a single scalar.

Implementations

impl EmlTree

pub fn new(depth: usize, input_count: usize) -> Self

Create a new EML tree specification.

Arguments

• depth: Tree depth (2, 3, 4, or 5).
• input_count: Number of input features.

Panics

Panics if depth is not in {2, 3, 4, 5}.

pub fn param_count(&self) -> usize

Number of trainable parameters for this tree configuration.

pub fn depth(&self) -> usize

Tree depth.

pub fn input_count(&self) -> usize

Number of input features.

pub fn evaluate(&self, params: &[f64], inputs: &[f64]) -> f64

Evaluate the tree with given parameters and inputs.

Arguments

• params: Trainable parameters (length must equal param_count()).
• inputs: Input feature values (length must equal input_count).

Panics

Panics if params.len() != param_count() or inputs.len() != input_count.
