flowmap.evaluation Module

Evaluation helpers for fitted FlowMap splines.

SplineFitEvaluator(emb, *, mode="default", spline=None, spline_vf=None, X_ref=None, V_ref=None)

Create an evaluator for expression and velocity reconstruction quality.

Parameters

• emb: fitted VectorFieldEmbedder.

• mode: "default", "gene", or "custom".

• spline: custom expression/reconstruction spline for mode="custom".

• spline_vf: custom velocity spline for mode="custom".

• X_ref: reference expression/features for mode="custom".

• V_ref: reference velocities for mode="custom".

Output

Returns a SplineFitEvaluator instance.

SplineFitEvaluator.evaluate(cell_idx=None)

Evaluate per-feature and mean reconstruction scores.

Parameters

• cell_idx: optional cells to evaluate.

Output

Returns a dictionary with expression and velocity R² and correlation scores.
