There are several practical difficulties with the widespread application of artificial neural networks to predictive data mining. The inscrutability of the fitted model limits their suitability for many database marketing applications and can even have legal ramifications in credit scoring applications. Other difficulties concern determining the(More)
With the routine use of computed tomographic imaging, intrinsic involvement of the genitourinary tract in newly diagnosed non-Hodgkin's lymphoma is seen in as many as 10 percent of patients. Incidental discovery of an extranodal, extra-lymphatic lesion in the genitourinary tract without clinical or radiographic evidence of disease elsewhere, however, is an(More)
We present a visual tablet for exploring the nature of a bagged decision tree (Breiman [1996]). Aggregating classifiers over bootstrap datasets (bagging) can result in greatly improved prediction accuracy. Bagging is motivated as a variance reduction technique, but it is considered a black box with respect to interpretation. Current research seekine: to(More)
The effects of alfalfa and orchardgrass diets of similar NDF content on ruminal digestion and digesta kinetics as measured using radiolabeled herbage were evaluated in Holstein cows. Two dry and two lactating cows, fitted with ruminal and duodenal cannulas, were fed 12 times daily at restricted and ad libitum intakes, respectively, in a crossover design.(More)
