  6. 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.

  13. 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.

  18. Near Infrared Light Reduces Inflammation via TLR4 In Vitro [2022]
    youtu.be/e6xj14QYsoc

    video discusses this article:
    Infrared light therapy relieves TLR-4 dependent hyper-inflammation of the type induced by COVID-19
    pmc.ncbi.nlm.nih.gov/articles/

    "The inflammatory response was induced in cell cultures by LPS, followed by exposure to 720 nm LED light source at an intensity of 6 W/m2 for 10 min at 12-h intervals (see methods). ... At the end of the 48-h treatment period, cells were harvested and gene expression analysis performed. The results showed an approximately 50% reduction in gene expression of all of these markers in response to LED infrared exposure (Figure 4). ..."

  22. ❌ Le Gouvernement ne respecte pas la loi qui l'oblige à évaluer sa politique à l'aune des nouveaux indicateurs de richesse #NIR

    Pourtant, l’impact des politiques menées sur notre santé, le niveau d’éducation ou l'environnement devrait être connu des parlementaires !

    ✍️ Notre courrier au Premier ministre

  23. 🟢 Il y a 10 ans jour pour jour, je faisais adopter la loi sur les Nouveaux Indicateurs de Richesse #NIR

    ❌ Mais depuis 2018, le Gouvernement ne la respecte plus !

    Nous devons connaitre l’impact des politiques menées sur notre santé, le niveau d’éducation ou l'environnement.

  26. where I discuss a neat way to include preprocessing techniques such as multiplicative scatter correction (MSC) in a #scikit_learn pipeline.

    MSC is one example of preprocessing techniques that are specific to #spectroscopy (esp. #optical and #nir )

  28. #Belfast to #Dublin (partially bustituted because of trackworks at the northern end of the line) with an #NIR #Translink Class 3000 unit. No @diningcar on this trainset, yet, before arriving at Dublin, a trolley service is available, selling some Irish stuff (and soft drinks).

  29. #Larne to #Belfast by #Translink #NIR Northern Ireland Railways Class 3000 diesel unit. Wonderful views as we pass right by the sea.

  32. Impressive lecture about light, near infrared (NIR) to be precise. The need to get outside, to get NIR (so it can penetrate the skin) and its health benefits for all animals, including humans. About the shortage that many are experiencing nowadays, since the use of white LED lights. And the disadvantages of blue light.

    Some interesting studies are discussed.
