In a precision era of hadron spectroscopy, new tools are required for the analysis of data from hadron reactions.
In this talk, we show an analysis of low-energy neutral pion photoproduction data using the
Least Absolute Shrinkage and Selection Operator (LASSO)
in combination with criteria from information theory
and $K$-fold cross validation. These analysis techniques
will become relevant in the near future. First, we illustrate these methods with synthetic data; then, the latest available measurements of differential cross sections ($d\sigma/d\Omega$),
photon-beam asymmetries ($\Sigma$), and target asymmetry differential cross sections
($d\sigma_T/d\equiv T\,d\sigma/d\Omega$) in the low-energy regime, are analyzed, and
its feasibility for real data is demonstrated.
