Linear

Full explanation on Linear Regression and the way it learnsEventually we arrived to a fairly good model. The true values I used to generate those numbers were and after only 50 iterations, the...

Some weeks ago, I published a post on LinkedIn.The post was based on the next figure, comparing the predictions made by two models: Linear Regression, and CatBoost.This began a discussion, and I discovered the...

A workflow and code walkthrough for constructing a Bayesian regression model in STANNote: Try my previous article for a practical discussion on why Bayesian modeling could also be the appropriate selection in your task.This...

Part 3: The algorithm under the hoodUp until now, this series has covered the fundamentals of linear programming. In this text, we're going to move from basic concepts into the main points under the...

Part 1 - Basic Concepts and ExamplesLinear programming is a strong optimization technique that's used to enhance decision making in lots of domains. That is the primary part in a multi-part series that may...

Explain regression to a non-technical audience with residual, weight, effect and SHAP plots“And don’t use any math” was my manager’s instruction.How else am I presupposed to explain how regression works!?Little did I do know...

We predict basis-free, we write basis-free, but when the chips are down we close the office door and compute with matrices like fury.Linear algebra is a fundamental discipline underlining anything one can do with...

The maths behind the model, from additive assumptions to pseudoinverse matricesTechnical disclaimer: It is feasible to derive a model without normality assumptions. We’ll go down this route since it’s straightforward enough to grasp and...
