I'm excited about Andrew Ng's upcoming Machine Learning class, but I know from the past YouTube videos that Andrew Ng has posted the course will be heavily dependent on strong knowledge of Linear Algebra.<p>I took Linear Algebra in college, but I don't remember any of it now 9 years later. What is your favorite concise primer/refresher on Linear Algebra?
Someone else recommend the Khan Academy lectures [1], and I was thinking about using those.<p>[1] <a href="http://www.khanacademy.org/#linear-algebra" rel="nofollow">http://www.khanacademy.org/#linear-algebra</a>
