The property that has given humans a dominant advantage over other species is not strength or speed, but intelligence. If progress in artificial intelligence continues unabated, AI systems will eventually exceed humans in general reasoning ability. A system that is “superintelligent” in the sense of being “smarter than the best human brains in practically every field” could have an enormous imp...

This article introduces (and hopes to encourage thereby) the econometrics practitioner to (use) a homoscedasticity test referred to in the field of statistics as the modified Levene test. Econometrics orthodoxy (from University to practice level) has focused mainly on three heteroscedasticity tests, namely the Goldfeld-Quandt (GQ), Breusch-Pagan-Godfrey (BPG), and the White (W) test. The differ...

Over the years, competitions have been important catalysts for progress in Artificial Intelligence. We describe one such competition, the Trading Agent Competition for Supply Chain Management (TAC SCM). We discuss its significance in the context of today’s global market economy as well as AI research, the ways in which it breaks away from limiting assumptions made in prior work, and some of the...

Power Quality is defined as the study of the quality of electric power lines. The detection and classification of the different disturbances which cause power quality problems is a difficult task which requires a high level of engineering expertise. Thus, neural networks are usually a good choice for the detection and classification of these disturbances. This paper describes a powerful tool, d...

Percent-done progress indicators are a technique for graphically showing how much of a long task has been completed. In the database environment such information is especially important during the long-running query execution. The proposed method constructs (during the learning phase) adaptive progress indicator model analyzing influence of averaged system state (represented with attributes des...

It is well known that the fate of transplanted tumors is controlled by the genetic relationship be tween the host and the tumor used for transplanta tion. This c@ncept has been accepted since the work of Little, Strong, Bittner, and others, as it has been reviewed by Bittner (1, 2), Little (5), Gorer (4), and Snell (9). In a study of some aspects of the growth of spontaneous and transplanted ma...

In the context of high performance computing (HPC), software investments in support of text-based diagnostics, which monitor a running application, are typically limited compared to those for other types of IO. Examples of such diagnostics include reiteration of configuration parameters, progress indicators, simple metrics (e.g., mass conservation, convergence of solvers, etc.), and timers. To ...
