Nearest Neighbors: Discussion – Lecture Notes

For a binary classification problem, with \(y\in \{ +1,-1\}\) , predict \[\begin{align*} \hat{y}(x) =& \begin{cases} +1 & \text{if } f(x) \geq 0 \\ -1 & \text{otherwise} \end{cases} \end{align*}\] Note: [...] Dimension of Nearest Neighbors Given a data set \(D\) , is there a \(k=1\) nearest neighbors classifier for each labeling? Yes, the 1-nearest-neighbor in \(D\) . ➜ VC-dimension of \(k\) NN is \(\infty\) [...] contradictions in the training data ( \(x_i=x_j\) , but \(y_i\neq y_j\) ), then \(k=1\) will have 100% accuracy in training ( \(1\text{NN}(x_i)=\{ i\}\) ). ➜ training error is not reliable for judging the quality …

Combining these inequalities yields f (xt)− f (xt−1)≥ f (xt−1 +λut)− [...] ∀ t2 > t1 > t0, f (xt2)− f (xt1) = ∑ t1<t≤t2 f (xt)− f (xt−1) < ε. Using proposition 15, we can write ∀ ε > 0, ∃ t0, ∀ t2 > t1 > t0, ‖xt2−xt1‖ ≤ ∑ t1<t≤t2 ‖xt −xt−1‖ ≤ ∑ t1<t≤t2 f (xt)− f (xt−1) K < ε K [...] attained inxt = xt−1 +λ∗ut . Let λ = νλ∗ with 0 < ν≤ 1. Sincext is a maximum, f (xt)− f (xt−1) = f (xt−1 +λ∗ut)− f (xt−1)≥ f (xt−1 +λut)− f (xt−1). Let H be the maximum overF of the norm of the Hessian …
