Extrapolating from Regularised Solutions for Solving Ill-Conditioned Linear Systems in Machine Learning

arXiv:2606.30328v1 Announce Type: cross Abstract: Rapid prototyping of algorithms is a critical step in modern machine learning. Most algorithms exploit linear algebra, creating a need for lightweight numerical routines which -- while potentially sub-optimal for the task at hand -- can be rapidly implemented. For the numerical solution of ill-conditioned linear systems of equations, the standard solution for prototyping is Tikhonov-regularised inversion using a nugget. However, selection of the size of nugget is often difficult, and the use of data-adaptive procedures precludes automatic diffe

Why this matters
Why now

The increasing complexity and scale of machine learning models necessitate more robust and efficient numerical methods for solving linear systems, particularly in ill-conditioned scenarios.

Why it’s important

Improving the speed and reliability of fundamental linear algebra operations directly impacts the efficiency of prototyping and deployment of new AI algorithms across various applications.
