Title: | Improving the Runtime Performance of Non-linear Mixed-Effects Model Estimation | Authors: | HABER, Tom VAN REETH, Frank |
Issue Date: | 2020 | Source: | Euro-Par 2019: Parallel Processing Workshops, p. 560 -571 | Series/Report: | Lecture Notes in Computer Science | Series/Report no.: | 11997 | Abstract: | Non-linear mixed effects models (NLMEM) are frequently used in drug development for pharmacokinetic (PK) and pharmacokinetic-pharmacodynamic (PK-PD) analyses. Parameter estimation for these models can be time-consuming due to the need for numerical integration. Additionally, the structural model is often expressed using differential equations requiring computationally intensive time-stepping ODE solvers. Overall, this often leads to long computation times in the order of hours or even days. Combining the right mathematical tools as well as techniques from computer science, the computational cost can be significantly reduced. In this paper, several approaches are detailed for improving the performance of parameter estimation for NLMEM. Applying these, often easy, techniques can lead to an order of magnitude speedup. | Document URI: | http://hdl.handle.net/1942/31383 | ISBN: | 978-3-030-48339-5 978-3-030-48340-1 |
