Report from discussions 30m
Items discussed at the meeting:
- Bayesian statistics to optimize experiments i.e. when do I have good statistics to stop measuring?
- How to treat variables correlations
- Resolution functions for small angle scattering
- Bayesian model comparison (how to select good model for fitting)
- Bayesian statistics as way to avoid overfitting
- Bayesian statistics and its relation to machine and deep learning
- How to make scattering communities aware of Bayesian statistics: constant presentation, highlight important results, show probability distribution
- Plotting distributions, Library for plotting
- Easy accessible software
- Can we have a "community prior"?
- Data format for prior and posterior to update
