If your #spectroscopy dataset is small, deterministic data subdivision into training and test sets may be the way to go 🔬
The SPXY algorithm is an extension of the Kennard-Stone method that selects training samples to maximize coverage of both spectra (X) and response variable (Y) at the same time.
Here's a primer, with a #Python implementation for #NIR spectroscopy.

It took a while, but I'm finally back to writing my blog 😎
The first installment for 2026 is an easy introduction to calculating information #entropy for optical spectra (or for any signal, really).
In my blog, I focus on #data analysis (#chemometrics, machine learning) applied to optical and near-infrared #spectroscopy Smoothing, or denoising, is one of the most common steps to work with spectroscopy data, and information entropy can be used as a criterion to guide the smoothing process.
Better still, the entropy of the derivative of a signal can help with that, because it accounts for the shape of the signal more naturally.

Drumquin residents voice strong opposition to proposed wind farm developments #NIR: Residents of Drumquin have raised growing concerns over plans for a series of new wind farm developments which they say could dramatically alter the character, landscape and quality of life in the village and surrounding hills. The concerns were highlighted on December 30, when around 60 people took part in a community walk around the Dooish and Dunnaree hills. The… https://www.wind-watch.org/news/2026/01/11/drumquin-residents-voice-strong-opposition-to-proposed-wind-farm-developments/ #windpower #windenergy
