Rank importance of parameters in a SimBiology model for parameter estimation. FeatureRanking computes
  • MRMR (minimum redundancy maximum relevance, [1])
  • NCA (neighborhood component analysis, [2])
  • F-TEST based feature ranking.
The ranking scores are computed from parameter samples and associated model simulations. The parameter samples are generated using a SimBiology.Scenarios object, the associated model simulations are computed using a SimBiology.SimFunction.Getting Started
Read and run driver.mlx for more details for how to use compute and plot ranking scores.
After installing this MATLAB Add-On, you can also type
>> help FeatureSelection
>> help FeatureSelection.histogram
in the MATLAB Command Window to get instructions for of how to use FeatureSelection.
This feature is supported in MATLAB® versions R2022a and later. Required products are SimBiology® and Statistics And Machine Learning Toolbox™.

Version Published Release Notes

Use 'results' instead of 'ranking' as out variable name in the example.


Fix: remove empty axes in histogram plots when reducing the number of plotted parameters via the NumParameters name-value argument.
