Smarter Aggregation: Minimizing Communication Costs in Polynomial Computing
![Compressed sensing, via the exploitation of orthogonality conditions detailed in Theorem 1 and minimized in Theorem 2, achieves feasibility with fewer responses-specifically [latex]N \leq d(K-1)[/latex]-than baseline individual decoding schemes, which require at least [latex]N \geq d(K-1) + 1[/latex] responses to ensure a viable solution, thereby demonstrating a fundamental efficiency gain in data acquisition.](https://arxiv.org/html/2601.10028v1/x1.png)
New research defines the limits of efficient data aggregation, revealing how to dramatically reduce the number of responses needed for weighted polynomial computations.
