I was in a similar situation. If you were left with a "So what" feeling then I imagine it would be difficult to plow through a general linear algebra book without having a feel for the end-game. Since you already took an introductory course, why not just start studying machine learning directly and learn the little linear algebra you need on the side? How much more linear algebra do you really think you need? Don't be a Depth-First-Search learner ;-) [1] [1] http://math.stackexchange.com/questions/617625/on-familiarity-or-how-to-avoid-going-down-the-math-rabbit-hole/617995#617995 http://math.stackexchange.com/questions/617625/on-familiarit...
