Great course on machine learning
For those looking to get a good (yet deep) understanding of machine learning, they could do worse than sign up for the course offered by Andrew Ng at Coursera.
The lectures are clear, the exercises make you think (and force you to code a bit) and the topics covered seem pretty practical (rather than just academic). While there’s clearly dross on MOOCs in general, this course is a goldmine. Highly recommended.
