Hi,
I am trying to use Sobol Global sensitivoity method (first and total order indices) to identify the significance of inputs which affects my output. For my problem, I have a trained neural network model and I want to implement Sobol method to identify the influence of each parameter. MATLAB has in-built function to give that "sbiosobol" but it uses SimBiology model (that needs separate model object). So, can anyone please help me with solving this problem. Is there alternate way to get those indices?
Regards,
Srinivas

Hi Srinivas,
I understand you want to use the 'Sobol' method for sensitivity analysis on your neural network model, but MATLAB's 'sbiosobol' function, designed for 'SimBiology', isn't compatible with your model.
While 'sbiosobol' is tailored for 'SimBiology' models, you can indeed perform global sensitivity analysis using alternative methods. To explore how to perform global sensitivity analysis outside the context of 'SimBiology', please visit the following MATLAB Central discussion link:-

I hope it helps,
Thanks and regards,
Akash.
