KNN and LR

if we increase N neighbors in KNN

• model overfits

• model underfits

in Logistic regression we

• maximize likelihood

• minimize likelihood

if we increase C in logistic regression

• model overfit

• model underfit

shortest distance between 2 points

• euclidean

• mahnaten

Cosine distance depends on

• euclidean distance

• angle between vectors

• number of neighbors
