Tcl is the original embeddable dynamic language. Introduced in 1990, Tcl has been the foundation of the scripting interface of the popular biomolecular visualization and analysis program VMD since 1995 and was extended to the parallel molecular dynamics program NAMD in 1999. The two programs together have over 200,000 users who have enjoyed for nearly two decades the stability and flexibility provided...
We seek to enable efficient large-scale parallel execution of applications in which a shared filesystem abstraction is used to couple many tasks. Such parallel scripting (many-task computing, MTC) applications suffer poor performance and utilization on large parallel computers because of the volume of filesystem I/O and a lack of appropriate optimizations in the shared filesystem. Thus, we design...
Paper deals with the problem of designing efficient classifiers for a special case of incremental concept drift. We focus on its classification based on the multiple classifier system. For the problem under consideration we propose four simple methods of combining classification and evaluate them via computer experiments.
The multiple classifier systems are nowadays one of the most promising directions in pattern recognition. There are many methods of decision making by the group of classifiers. The most popular are methods that have their origin in vote methods, where the decision of the common classifier is a combination of simple classifiers decisions. There exists a trend of combined classifiers, which are making...
Boosting is the most popular method of improving quality and stabilizing weak classifiers. It bases on the voting by the group of classifiers, where each of them is generated on the basis of modified original learning set. The modification of AdaBoost.M1 and experimental results of boosted C4.5 (decision tree induction) algorithm are presented. All experimental researches are made on well known benchmark...
