These algorithms allow computers do things like automatically identify and harness useful data to help decision making, find hidden insights without being explicitly programmed where to look, and predict outcomes to help authorities design effective policies. You'll graduate with skills at the forefront of this massive growth area, as society looks for automated solutions to enhance business and our lives through the use of computing systems and data. These skills can be applied in government departments, consultancy or private sector organisations.

JUDY WOODRUFF: Now we continue our special series on Rethinking College with a look at graduate students who pay little or even nothing for a top 10 master's degree program. HARI SREENIVASAN: It's graduation day, and these two students are earning their computer science master's degree from a top 10 program in the country. But it's the first time they have ever visited campus. VANESSA ANDERSON, Graduate: This whole experience was very surreal. This is my first time on campus, being here.
