Most likely the percentage will be much higher. I'm saying that as a former dropout :) I've decided to go through the Machine Learning course (the web version) few months ago but it's really too math heavy. It's not that I'm a total noob but having to parse formulas spanning 2 rows and containing half the Greek alphabet is about as exciting as reading an organic chemistry textbook.

Nevertheless I signed up! But I hope some day there will be a AI/machine learning course that will have code examples for every concept and every math formula, just like this: http://www.cleveralgorithms.com/nature-inspired/index.html Maybe it's just me but code is way easier to read and understand.

I suspect more will drop out since they have even less necessity driving them than someone at community college.

That's still 14500 who won't.

We should run a betting pool for this. I'd bet at even money than more than 90% of online signups fail to complete the course. Give me decent odds and I'll bump that up to 95%
