Not All Objectives Are Born Equal: Priority-Constrained Descent for Hierarchical Multi-Objective Optimization
arXiv:2606.29521v1 Announce Type: new Abstract: Deep learning problems rarely involve objectives that are equal in importance. A primary objective defines the goal, whilst secondary objectives, such as sparsity, compression, or robustness constrain the solution. While existing multi-objective methods have proven effective in practice, they have a clear symmetry problem and neglect the inherent objective hierarchy built into these objective spaces. We introduce Priority-Constrained Descent (PCD), a gradient-based optimization framework designed to explicitly exploit hierarchical objective struc
This research addresses a fundamental limitation in current multi-objective optimization for deep learning, leveraging the increasing complexity and multi-faceted requirements of advanced AI models.
Improving the efficiency and effectiveness of multi-objective optimization directly impacts the development of more robust, scalable, and specialized AI systems, particularly for applications requiring trade-offs like sparsity or safety.
This framework offers a principled way to incorporate objective hierarchies into deep learning optimization, moving beyond 'symmetric' multi-objective approaches that treat all goals equally.
