Article Title: Bayesian optimisation for efficient parameter inference in a cardiac mechanics model of the left ventricle

doi: 10.1002/cnm.3593

Figure Lengend Snippet: Basic study: convergence of the objective function f O 2 for Bayesian optimisation and the original HGO algorithm for four LV geometries (HV A, HV B, HV C, HV D). Horizontal axis: Bayesian optimisation iterations starting from 40 iterations for the initial design. Vertical axis: best value of the objective function f O 2 recorded so far. Black dot and horizontal dashed line: the final value of the objective function f O 2 for the HGO algorithm and the associated number of iterations. Bayesian optimisation with a target surrogate (target) and a partial error surrogate (partial) together with the old version of the HGO algorithm (HGO old)

Article Snippet: For these reasons we use a different approach based on a global optimisation algorithm called OQNLP (or Global Search in its implementation in MATLAB's Global Optimisation toolbox that we use), which led to very stable results.

Figure Lengend Snippet: Klotz‐curve study: convergence of the objective function f O 2 , Klotz for Bayesian optimisation and the original HGO algorithm for four LV geometries (HV A, HV B, HV C, HV D). Horizontal axis: Bayesian optimisation iterations after 40 iterations for the initial design. Vertical axis: best value of the objective function f O 2 recorded so far. Black dot and horizontal dashed line: the final value of the objective function f O 2 for the HGO algorithm and the associated number of iterations. Bayesian optimisation with a target surrogate (targ.) and a partial error surrogate (part.), three independent runs (v1, v2, v3) in each version, together with the new version of the HGO algorithm (HGO new). For HGO, the Klotz curve error was computed using the forward simulator (not the emulator)

Article Snippet: For these reasons we use a different approach based on a global optimisation algorithm called OQNLP (or Global Search in its implementation in MATLAB's Global Optimisation toolbox that we use), which led to very stable results.
