Please describe your attempt to perform UQ on your application, include UQ method/sampling, the type of uncertainty considered, use case, inputs/outputs etc. What types of UQ did you have the opportunity to implement? What use cases did you attempt to perform UQ on for your application? What did you achieved? Did you perform UQ on a single- or multi-model simulation?

After your participation in the hackathon, what is your current view on your needs in terms of UQ for the Neptune project?
No responses yet for this question.
If you were able to use non-intrusive methods, which sampling methods did you use? Do you think that the most performant ones (such as dimension-adaptive sampling) could be used effectively as part of the Neptune project? Please briefly explain your answer (max. 500 words)

What is your view on the role of surrogate modelling in applications? What benefits do you anticipate from using surrogate models (e.g. Gaussian processes, neural networks)? Are there any limitations in their use which concern you? (max. 500 words)
No responses yet for this question.
If you had the time to consider implementing surrogates, please explain how you envisage setting them up and using them within your application (max. 300 words)
