Expand description

A discovered law and its quality.

Fields§

§tree: ANode

The fitted tree (its forward IS the prediction; see Self::predict).

§mse: f64

Mean-squared error on the fitting data.

§r2: f64

Coefficient of determination.

§expr: String

Readable expression.

§nodes: usize

Complexity (nodes + active coefficients).

§depth: usize

Tree depth.

§symbolic: bool

Whether the law is a symbolic recovery: every structural exponent/slope snaps to a small rational / named constant while retaining R² ≥ 0.999 (set by Self::with_snap).

Implementations§
