Data leakage in ML for biological and clinical data: what it is and how to avoid it

When we build machine learning models on biological or clinical data, data leakage is one of the fastest ways to get results that look amazing on paper and fail spectacularly in reality.

Image analysis in ML pipelines for biology: a maths-and-plots guide

Biological image analysis is where measurement meets models. A microscope image is not “just pixels”: it’s a noisy sampling of an underlying biological scene (cells, nuclei, organelles), transformed by optics, staining, sensor noise, and experimental variability.

Maths notation as a language: sets, symbols, and what they mean

A lot of the fear around maths comes from notation: curly letters, upside-down letters, and symbols that look like hieroglyphics. The good news is that maths notation is just a language. Once you learn the vocabulary and grammar—what each symbol means and how phrases are combined—equations stop being cryptic and start saying something clear. In this post I’ll treat notation as language, focus on set notation (the “nouns” of many mathematical statements), and illustrate the main ideas with plots.

Random Forests vs Gaussian Processes: A Practical Maths-First Comparison

Random Forests and Gaussian Processes (GPs) are both powerful non‑parametric models (models that don’t fix a single, limited functional form in advance) for regression and classification, but they come from very different mathematical worlds.
