| lg_mj1_parameterize_positive_diffusivity_{de}lithiation_[({n},{n}+2)]_{model}()_optimization.log | Direct command line log of the EP-BOLFI optimization routine of data segments {n} and {n+1} and of {model} from SPM, SPMe, or DFN, for positive electrode diffusivity in (de-)lithiation direction. | PDF (text/plain) |
Check of the performance and efficiency with the given optimizer settings, and possibly retrieval of intermediate results. |
| lg_mj1_parameterize_positive_diffusivity_{de}lithiation_[({n},{n}+2)]_{model}()evaluations.json | Structured dump of all parameter sets EP-BOLFI tried out and the feature values the SPM, SPMe, or DFN {model} gave of data segments {n} and {n+1} for positive electrode diffusivity in (de-)lithiation direction. | JSON (application/json) |
Post-processing of convergence and analysis of posterior predictive distribution. |
| lg_mj1_parameterize_positive_diffusivity_{de}lithiation_[({n},{n}+2)]_{model}()_parameterization.json | Structured dump of results and inner state of EP-BOLFI at the end of the optimization routine of data segments {n} and {n+1} and of {model} from SPM, SPMe, or DFN, for positive electrode diffusivity in (de-)lithiation direction. | JSON (application/json) |
Programmatically retrieve mean results, errorbars, and correlation or covariance. May be used to re-initialize an EP-BOLFI instance with the final state for further refinement optimization. |
| lg_mj1_parameterize_positive_diffusivity_{de}lithiation_optimizer_input_[({n},{n}+2)]_{model}()_plot.pdf | Plot showing the data of data segments {n} and {n+1} and the simulation of the mean of the posterior parameter distribution of {model} from SPM, SPMe, or DFN, for positive electrode diffusivity in (de-)lithiation direction and the extent of variation of the model within posterior variance and without inherent parameter uncertainty. | PDF (application/pdf) |
Visual verification that the posterior parameter distribution is a sensible parameterization. |
| lg_mj1_parameterize_positive_diffusivity_{de}lithiation_optimizer_input_[({n},{n}+2)]_{model}()_voltage_components.pdf | A component analysis of the mean posterior parameter distribution simulation of {model} from SPM, SPMe, or DFN, for positive electrode diffusivity in (de-)lithiation direction. | PDF (application/pdf) |
Visual analysis of the relative magnitude of various battery phenomena, and if the desired one has the expected effect. |
