Ask Slashdot: How To Get Into Machine Learning?

An anonymous reader writes: I know this is a vague question, but hoping to get some useful feedback anyway. I'm an experienced SW Engineer/Developer who is looking to get into the Machine Learning arena. I have an MS in CS and a solid 15 years of experience in a variety of areas, but no experience in Machine Learning.With that as background, my question is: What is the most time-efficient (and reasonable cost) way to:
(1) Decide whether Machine Learning is for me and
(2) Make myself employable in the field.
An additional constraint is that I can't afford to quit my full-time day job. Thanks.
