## The convergence rate of the OLS estimator for linear regression

A lot of machine learning and modern statistics concerns the rate at which certain statistical estimators converge to the quantities they are estimating. For instance, in classification, you use a collection of observations of covariates $$\mathbf{x}_i \in \mathbb{R}^p$$ and classifications $$y_i \in \{\pm 1\}$$ to fit an estimated classification function \(h : \mathbb{R}^p \rightarrow […]

I stopped watching after the first episode of season 3, in part because the American version came out and I got into that before it started circling the drain, and in part because Mitchell gets on my damned last nerve.
