I have an B.A. in philosophy and would like to continue on this track by eventually pursuing a career working on artificial intelligence. To do this I will need to get a masters in computer science but my liberal arts background does not provide me with enough prerequisite qualifications to do so. I have heard there are post baccalaureate certificate programs for non-computer science degree holders with which you can obtain enough foundation to be able to qualify for some masters programs. What are some good programs for doing this? Ones which lead directly into an artificial intelligence program would be ideal. If there is a better way of going about this that would be useful to know as well.
