The traditional goal of computer vision, to reconstruct, or recover properties of, the scene has recently been challenged by advocates of a new purposive approach in which the vision problem is defined in terms of the goals of an active agent. In the starkest light the debate can be characterized as one about the role of explicit representations. The extreme traditionalists strive for a detaile...

Recently, two clinical trials of novel agents in metastatic ovarian cancer were published: a phase 3 study of nintedanib and a phase 2 study of volasertib. There seemed to be discordance between the results and conclusions in the publication of both these trials. Despite not very optimistic results, the studies concluded optimistically in favor of the new agents under study. Using these example...

The functional paradigm is a common choice for the first course in computing in many European universities, especially in the United Kingdom, but a prominent role for the functional paradigm is rare in computing programs in the United States. Introducing the idea is difficult, partly because so few programs use functional methods that qualified instructional staff, at both the faculty and gradu...

High-level scripting languages are in many ways polar opposites to GPUs. GPUs are highly parallel, subject to hardware subtleties, and designed for maximum throughput, and they offer a tremendous advance in the performance achievable for a significant number of computational problems. On the other hand, scripting languages such as Python favor ease of use over computational speed and do not gen...
