What are Bayesian networks and why are their applications growing across all fields?

Compressive sampling (CoSa) is a new paradigm for developing data sampling technologies. It is based on the principle that many types of vector-space data are compressible, which is a term of art in mathematical signal processing. The key ideas are that ...

The interactive proof system model of computation has been studied extensively in computational complexity theory and theoretical cryptography for more than 25 years, and has driven the development of interesting new techniques and insights in those ...

It's amazing how little we know about the simple, ordinary, axis-aligned rectangle. Last month (p. 112) we posted a trio of brainteasers, including one as yet unsolved, concerning rectangles galore. Here, we offer solutions to at least two of them. How ...

Future Tense, one of the revolving features on this page, presents stories and essays from the intersection of computational science and technological speculation, their boundaries limited only by our ability to imagine what will and could be.
