Python Modules

specrecon.toy_data

• Generates the toy regression dataset used in the model-selection section.

specrecon.polynomial

• Polynomial fitting utilities.
• Vandermonde design-matrix construction.
• Gaussian log-likelihood.
• Bayesian posterior coefficients and polynomial-model evidence.

specrecon.plotting

• Plot helpers extracted from the notebook.
• Keeps visualization code separate from the numerical routines.

specrecon.spectral

• Frequency-grid construction.
• RBF prior kernel helpers.
• Response-matrix construction.
• Spectral marginal likelihood and posterior helper utilities.

specrecon.sampling

• Sequential posterior updates.
• Adaptive sampling loop.
• Random sampling loop.

Notes

• The notebook is still kept in notebooks/ as the main exploratory document.
• Reusable Python code has been pulled into src/specrecon/ so the project is no longer notebook-only.
• The package uses clearer ASCII function names internally, while keeping a few notebook-style aliases for compatibility.
• pyproject.toml defines a minimal installable package plus optional extras for plotting and notebook work.
• The figure outputs and the PDF reference were moved out of the repository root to keep the top-level layout focused.
• The notebook expects additional experiment data such as interferogram_spectrum.npz, but that file is not present in this repository.

Install

pip install -e .

Install notebook-related dependencies if you want to rerun the notebook:

pip install -e .[notebook]
