Quantifying the Reconstructability of Astrophysical Methods with Large Language Models and Information Theory: A Case Study in Spectral Reconstruction

arXiv:2605.11154v2 Announce Type: replace-cross Abstract: Modern astrophysical studies rely heavily on complex data analysis pipelines; however, published descriptions often lack the detail required for computational reproducibility. In this work, we present an information-theoretic framework to quantify how effectively a method can be reconstructed from its written description. By treating algorithmic reconstruction as a probability distribution generated by Large Language Models (LLMs), we utilize Shannon entropy and Jensen-Shannon divergence to measure how strongly text constrains the hypot

Why this matters
Why now

The proliferation of complex AI models and the increasing demand for scientific reproducibility are converging, making a quantifiable framework for method reconstructability crucial.

Why it’s important

This work introduces a novel, quantifiable method for assessing the reproducibility of scientific methodologies, using LLMs and information theory, which is vital for trust and progress in complex scientific fields.

What changes

The ability to objectively measure how well scientific methods can be reproduced from their descriptions will lead to more robust scientific practices and potentially influence publication standards.
