This article builds linear regression from a five-point example to the normal equations, shows why least squares is a projection and a maximum-likelihood estimate at the same time, trains it with gradient descent you can steer, and then puts it to work on a real dataset to see where it holds up and where it breaks. 48 min read · [siddheshsawant.hashnode.dev](https://siddheshsawant.hashnode.dev/linear-regression?utm_source=hashnode&utm_medium=feed) [Milo](https://hashnode.com/@miloarchive) · [Nov 1](https://hashnode.com/posts/demystifying-ols-the-engine-behind-linear-regression/6ae7b0cc3d76d6a5fcbd2c4a) ### [Demystifying OLS: The Engine Behind Linear Regression](https://blog.miloarchive.com/demystifying-ols-the-engine-behind-linear-regression?utm_source=hashnode&utm_medium=feed) Explore OLS linear regression mechanics, its vulnerability to outliers and multicollinearity, and how Ridge and Lasso regularisation fix its limits. 5 min read · [blog.miloarchive.com](https://blog.miloarchive.com/demystifying-ols-the-engine-behind-linear-regression?utm_source=hashnode&utm_medium=feed) [Kehinde Onasanya](https://hashnode.com/@kehindeonasanya) · [Oct 29](https://hashnode.com/posts/linear-regression-from-scratch/6ae29b0c87ba056803a12f18) ### [Linear Regression From Scratch](https://kehindeonasanya.hashnode.dev/linear-regression-from-scratch?utm_source=hashnode&utm_medium=feed) Linear regression is one of the fundamental algorithms in supervised machine learning.
