Researchers have developed a novel approach to symbolic regression by extending the Equation Learner model to operate in the complex domain. This method addresses limitations of traditional gradient-based techniques that struggle with mathematical operators like division and logarithms, which can introduce singularities. By allowing optimization trajectories to bypass real-axis degeneracies, the Complex Equation Learner can stably converge even when target expressions have real-domain poles, enabling the unconstrained use of functions such as logarithms and square roots.
