Robust Parameter Identifiability Analysis via Column Subset Selection

Katherine J. Pearce, Ilse C. F. Ipsen, Mansoor A. Haider +2

We advocate a numerically reliable and accurate approach for practical parameter identifiability analysis: Applying column subset selection (CSS) to the sensitivity matrix, instead…

Precision-aware Deterministic and Probabilistic Error Bounds for Floating Point Summation

Eric Hallman, Ilse C. F. Ipsen

We analyze the forward error in the floating point summation of real numbers, for computations in low precision or extreme-scale problem dimensions that push the limits of the prec…

Monte Carlo Methods for Estimating the Diagonal of a Real Symmetric Matrix

Eric Hallman, Ilse C. F. Ipsen, Arvind Saibaba

For real symmetric matrices that are accessible only through matrix vector products, we present Monte Carlo estimators for computing the diagonal elements. Our probabilistic bounds…

Deterministic and Probabilistic Error Bounds for Floating Point Summation Algorithms

Eric Hallman, Ilse C. F. Ipsen

We analyse the forward error in the floating point summation of real numbers, from algorithms that do not require recourse to higher precision or better hardware. We derive informa…

SEAGLE: A Scalable Exact Algorithm for Large-Scale Set-Based GxE Tests in Biobank Data

Jocelyn T. Chi, Ilse C. F. Ipsen, Tzu-Hung Hsiao +5

The explosion of biobank data offers immediate opportunities for gene-environment (GxE) interaction studies of complex diseases because of the large sample sizes and the rich colle…
