Interactive post-thesis extensions

Live demonstrations, with the limits visible.

These applications make retained classifier artifacts explorable. They are demonstrations of restricted synthetic comparisons—not observational inference services or tools for determining the composition of a real star. They are also independent of the BSk24 arXiv preprint.

Shared interpretation boundary

The displayed values are uncalibrated model scores. Input uncertainty is represented by independent Gaussian samples rather than real NICER or LIGO posterior samples. The central 95% score range is not a confidence interval or composition posterior, and SHAP explains fitted-model behaviour rather than physical truth.

01 · Baseline demonstration

APR-1-surrogate versus fixed-CFL4 scores

Explore how a retained classifier responds to selected mass, radius, and tidal inputs inside one restricted synthetic model comparison.

  • Restricted repository-model comparison
  • Independent Gaussian input sampling
  • Uncalibrated classifier scores

02 · Perturbation sensitivity

Synthetic perturbations, without compactness as a feature

Explore score sensitivity in the retained perturbed workflow. This tests one declared synthetic error construction; it does not reproduce observational uncertainty.

  • Compactness excluded from classifier inputs
  • Mass–radius and mass–radius–tidal modes
  • No phase-general or observational claim

Development boundary

Independent post-thesis extensions.

The demonstrations were developed after the thesis as separate classification extensions. They are not thesis-submission artifacts, observational inference services, or official companion applications to the BSk24 preprint. Scientific interpretation and responsibility remain with Ioannis Papathanasiou.
