STK2100 - Maskinl?ring og statistiske metoder for prediksjon og klassifikasjon

Weekly exercises

Here you find the weekly exercises for the coming week, as well as an overview of exercises for past weeks. The week number refers to when the exercises will be discussed in the exercise class.

To learn the material well, it is important to spend time and make real efforts on trying to solve the exercises, preferably before the exercise class.

Some of the exercises are from the book James et al 2013: An Introduction to Statistical Learning, and will be referred to as ISLR

Exercises from ISLR: 2.1, 2.2, and 2.8 (see the webpage for the book for downloading data; the easiest alternative is to install the ISLR library (through the command install.packages("ISLR")), make the library available (through the library("ISLR")), and then make the data available through data(College)).
