  1. 📣 Wednesday 15th July, at 16:00 CET, I'll be hosting a webinar presented by Dr Mercedes Bertotto (Wittenborg University):

    "Bridging Model Validation and Analytical Validation in Spectroscopy: The Role of the Accuracy Profile"

    The idea behind the talk is to highlight that validation of #chemometrics models alone is often not sufficient. In addition to classical model validation approaches, analytical validation, traditionally used in analytical chemistry and laboratory testing, should also be applied in chemometrics and #spectroscopy workflows to ensure true method performance and reliability.

  16. 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.

  21. 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.

  43. ☕ Here's a bit of technical content from me - today a deep dive on #baseline correction methods.

    📈 Baseline correction is a preprocessing technique to remove background signal and isolate peaks in hashtag#spectroscopy data.

    📝 In my recent post I discuss two methods:
    1. Wavelet transform (WT) - Decomposes signal into components at different frequencies. Lowest frequency component represents baseline and can be removed.
    2. Asymmetric least squares (ALS) - Fits a smooth baseline function, penalising positive deviations more than negative ones.

    TL;DR: WT method is intuitive but can distort peaks. ALS produces better results.

    🔎 Both methods are applied on a #Raman spectrum and an X-ray fluorescence (#XRF) spectrum. ALS gives a cleaner baseline correction and it's effective for removing broad, slowly varying background while preserving sharper spectral features.

  49. 📯 New blog post: "
    Wavelength selection with a genetic algorithm"

    If you're interested in #spectroscopy, especially NIR or Raman, or #chemometrics, a suitable selection of wavelength bands is often needed to produce a good statistical model.

    Genetic algorithms are optimisation procedures loosely inspired by the mechanism of evolution by natural selection.

    In this point, I'm working through an example of variable selection with a genetic algorithm for regression.
