A new procedure for combined validation of learning models - developed for specifically uncertain data - is briefly described; it relies on a combination of resubstitution with the modified learn-and-test paradigm, called by us the queue validation. In the initial experiment the elaborated procedure was checked on doubtful (presumably distorted by creative accounting) data, related to small and medium...
This paper presents a methodology based on rough set theory that can be used to identify those newborn with congenital heart diseases for which performing the test is redundant or superfluous. Pawlak introduced rough set theory in the early 1980s as a tool for representing and reasoning about imprecise or uncertain information. Our method depends on cardiac morphologic measurement algorithms for diagnosis...
This paper compares the application of three different dimension reduction techniques to the problem of classifying functions in object code form as being cryptographic in nature or not. A simple classifier is used to compare dimensionality reduction via sorted covariance, principal component analysis, and correlation-based feature subset selection. The analysis concentrates on the classification...
In this paper, a neural architecture which gives identical TSK fuzzy system is proposed based on the area selection concept in neural network design. Instead of using traditional membership functions for selection the range of operation, the monotonic pair-wire or sigmoidal activation function is used. In the comparison to popular neuro-fuzzy systems, the proposed approach does not require signal...
Patients with a tremor find it often very difficult to handle IT Systems and therefore attain very low levels of efficiency when doing so. The currently available user interfaces do not guarantee a sufficient precision when data input and selection is performed. People suffering from a intention tremor observe a significant increase in their tremor when approaching their input “destination” on the...
Previous studies of depth and distance estimation with autostereoscopic 3D displays indicate the users do not necessarily exhibit better depth perception with such displays. Yet, users claim 3D displays provide higher immersiveness. As shapes of objects are often described by their angles, it is expected that angle perception would contribute to object recognition and scene understanding. However;...
Mobile communication services and Location based services are challenging application areas of wireless communications. Many applications were developed which require mobile navigation. The most known navigation systems are car navigation systems. Fewer advances have been made in pedestrian navigation systems (PNSs). There are some targeted achievements but the most challenging task is to develop...
Uniform Resource Locator (URL) ordering algorithms are used by Web crawlers to determine the order in which to download pages from the Web. The current approaches for URL ordering based on link structure are expensive and/or miss many good pages, particularly in social network environments. In this paper, we present a novel URL ordering algorithm that exploits the access count information present...
