abstract = "... are passed to an external learner to model the
target task. This approach enables any function
approximator, from linear models to neural networks, to
serve as a lifetime learner, allowing expressive
modeling beyond conventional symbolic forms. We show
that LaSER can outperform standard GP, particularly
when equipped with nonlinear lifetime learners. While
LaSER with linear models (e.g., ridge regression)
already offers strong performance on smooth,
low-complexity problems, its true advantage emerges as
target functions grow in nonlinearity and complexity
where nonlinear learners provide a stronger inductive
bias. We also present a first attempt at demonstrating
an instance of the Baldwin Effect in symbolic
regression: under LaSER, evolved representations become
increasingly innate, reducing reliance on lifetime
learning across generations. By explicitly separating
the roles of representation and adaptation, LaSER
offers a principled and extensible framework for
symbolic modeling tasks.",
