arXiv:2606.23939v1 Announce Type: cross Abstract: Variable projection is a classical technique for separable nonlinear least-squares problems, in which variables that enter linearly are eliminated exactly, yielding a reduced nonlinear problem. By expressing this framework as a particular instance of a broader class of bilevel optimization problems, we develop a constrained variable-projection framework for data-science models, where the remaining variables are subject to convex constraints and the eliminated variables arise from a lower-level least-squares problem. In particular, by interpreti
This research builds on classical optimization techniques, adapting them for the growing complexity and scale of modern data science problems, which are increasingly central to AI development.
Improved optimization techniques for complex data-science models will enhance the efficiency and capability of AI systems, potentially accelerating advances in machine learning and autonomous agents.
The constrained variable projection framework provides a more robust and flexible approach to solving certain classes of bilevel optimization problems, offering better performance for models with linear substructures and convex constraints.
