title: 'leaf: Learning Equations for Automated Function Discovery'
version: 0.1.0
doi: 10.32614/CRAN.package.leaf
abstract: 'A unified framework for symbolic regression (SR) and multi-view symbolic
  regression (MvSR) designed for complex, nonlinear systems, with particular applicability
  to ecological datasets. The package implements a four-stage workflow: data subset
  generation, functional form discovery, numerical parameter optimization, and multi-objective
  evaluation. It provides a high-level formula-style interface that abstracts and
  extends multiple discovery engines: genetic programming (via PySR), Reinforcement
  Learning with Monte Carlo Tree Search (via RSRM), and exhaustive generalized linear
  model search. ''leaf'' extends these methods by enabling multi-view discovery, where
  functional structures are shared across groups while parameters are fitted locally,
  and by supporting the enforcement of domain-specific constraints, such as sign consistency
  across groups. The framework automatically handles data normalization, link functions,
  and back-transformation, ensuring that discovered symbolic equations remain interpretable
  and valid on the original data scale. Implements methods following ongoing work
  by the authors (2026, in preparation).'
