Web30 Oct 2024 · For example at page 18, there is the MSE which fails to explain (IMO) the "E". Similarly at page 22 when the concept of "regularization" is explained, we can argue that the whole section could be "keep it simple with the linear function" and the reader would get the same information instead of these many paragraphs. Web17 May 2024 · Regression models are models which predict a continuous outcome. A few examples include predicting the unemployment levels in a country, sales of a retail store, number of matches a team will win in the baseball league, or number of seats a party will win in an election.
