A Second-Moment Theory for Floating-Point Reduction Trees

Piyush Sao, Narasinga Miniskar, Pedro Valero-Lara +2

Summation error depends on partial-sum order, which standard worst-case bounds omit. To capture this dependence, we derive an exact mean-square error (MSE) recurrence for a binary…

Fast Evaluation of Truncated Neumann Series by Low-Product Radix Kernels

Piyush Sao

Truncated Neumann series $S_{k} (A) = I + A + \dots + A^{k - 1}$ are used in approximate matrix inversion and polynomial preconditioning. In dense settings, matrix-matrix products dominate the…
