Data notes, models and stories

The Data Notebook

A home for model experiments, production lessons, and the kind of data stories that start in a notebook and end in a dashboard.

Coming Soon

A preview of the first set of posts lined up from the writing queue, ready to move from working notebooks into polished, shareable articles.

Markov chains visualized on a state diagram Markov Models

Markov Chains And The Art Of Next Best Move

Data Science · Probability

A walk through Markov chains, transition matrices, and how state based thinking can power real world decision systems, from customer journeys to maintenance schedules and everything in between.

Ensemble models and layered decision boundaries Ensemble Modelling

Why One Model Is Rarely Enough

Machine Learning · Ensembles

From bagging and boosting to stacking, a look at ensemble modelling as a team sport for algorithms, where combining slightly imperfect players often beats the star model trying to do everything alone.

Bayesian statistics visual with priors and posteriors Bayesian Thinking

Bayesian Intuition For Everyday Decisions

Statistics · Reasoning

Turning priors, likelihoods, and posteriors into something human. A practical look at Bayesian statistics as a way to update beliefs, not just a chapter in a textbook everyone promises to revisit later.

Before the posts land

Want to turn one of these topics into a real project?

If you are thinking about experimentation, dashboards, or production ready models, we can skip straight to a working session and shape something concrete around your data.
