Graded Signal Functions for ARTMAP Neural Networks
This study presents an analysis of a modified ARTMAP neural network in which a graded signal function replaces the standard choice-by-difference function. The modifications are introduced mathematically and the performance of the system is studied on two benchmark examples. It is shown that the modified ARTMAP system achieves classification accuracy superior to that of standard ARTMAP, while retaining comparable complexity of the internal code.Office of Naval Research and the Defense Advanced Research Projects Agency (N00014-95-1-0409, N00014-1-95-0657
Artificial neural networks in geospatial analysis
Artificial neural networks are computational models widely used in geospatial analysis for data classification, change detection, clustering, function approximation, and forecasting or prediction. There are many types of neural networks based on learning paradigm and network architectures. Their use is expected to grow with increasing availability of massive data from remote sensing and mobile platforms
Impact of School-Based Sex Education on College Students’ Rape Myth Acceptance: An Exploratory Analysis
Research indicates nearly one-fourth of college women fall victim to sexual assault (Cantor et. al., 2015). Two predictors of high proclivity to rape are endorsement of rape myths and adherence to traditional gender norms (King & Roberts, 2011). Additionally, research shows school-based sex education in the United States presents gender and sexual norms in troubling ways that disproportionately harm women (Kendall, 2013). However, research on sexual assault and rape myths have not examined the impact school-based sex education has on rape supportive attitudes. This study aimed to bridge that gap by using original survey data from undergraduate students at a large public university. Analyses indicate sex education has an inconsistent impact on rape myth acceptance; additionally, seeking sexual health information online was found to significantly lower endorsement of rape myths. Study outcomes suggest that further research is needed to explore the relationship between sex education curricula and rape supportive attitudes
Legal Education Unbundled (and Rebundled)
This essay calls for an unbundling of legal education, much like the kind of unbundling we have seen in the cable, music, and print news media. It suggests that the standard legal education bundle -the generalized JD-is just one of many forms of legal education that can be packaged appropriately for today\u27s legal education market needs
ART Neural Networks: Distributed Coding and ARTMAP Applications
ART (Adaptive Resonance Theory) neural networks for fast, stable learning and prediction have been applied in a variety of areas. Applications include airplane design and manufacturing, automatic target recognition, financial forecasting, machine tool monitoring, digital circuit design, chemical analysis, and robot vision. Supervised ART architectures, called ARTMAP systems, feature internal control mechanisms that create stable recognition categories of optimal size by maximizing code compression while minimizing predictive error in an on-line setting. Special-purpose requirements of various application domains have led to a number of ARTMAP variants, including fuzzy ARTMAP, ART-EMAP, Gaussian ARTMAP, and distributed ARTMAP. ARTMAP has been used for a variety of applications, including computer-assisted medical diagnosis. Medical databases present many of the challenges found in general information management settings where speed, efficiency, ease of use, and accuracy are at a premium. A direct goal of improved computer-assisted medicine is to help deliver quality emergency care in situations that may be less than ideal. Working with these problems has stimulated a number of ART architecture developments, including ARTMAP-IC [1]. This paper describes a recent collaborative effort, using a new cardiac care database for system development, has brought together medical statisticians and clinicians at the New England Medical Center with researchers developing expert systems and neural networks, in order to create a hybrid method for medical diagnosis. The paper also considers new neural network architectures, including distributed ART {dART), a real-time model of parallel distributed pattern learning that permits fast as well as slow adaptation, without catastrophic forgetting. Local synaptic computations in the dART model quantitatively match the paradoxical phenomenon of Markram-Tsodyks [2] redistribution of synaptic efficacy, as a consequence of global system hypotheses.Office of Naval Research (N00014-95-1-0409, N00014-95-1-0657
Analogous: Digital / Analogue Metaphors.
When discussing our understanding of the world, the term ‘analogue’ has become shorthand for anything not digital, and has become an analogy of its own. ‘Digital’ has also become an analogy for anything requiring a computer. This essay starts to investigate some of the analogies of analogue and digital media to reveal the complexity of thinking about animation
