Some Culp Family Members in the Civil War

In the 1860s Gettysburg had a population of around 2,400. The Culps had lived there since 1787, the year Christopher Culp purchased the farm, located on the east end of town, with its western boundry starting at Baltimore St. between Breckenridge and South Streets, going northeast to South Stratton St. and Wall Alley East, then on to East Middle St. between South Stratton and Liberty Streets. The town more or less ended at the farm boundary. Prominent on the farm and southeast of town was Culp\u27s Hill. Five generations of Culps had lived in Gettysburg by the time of the battle.

ada: An R Package for Stochastic Boosting

Boosting is an iterative algorithm that combines simple classification rules with "mediocre" performance in terms of misclassification error rate to produce a highly accurate classification rule. Stochastic gradient boosting provides an enhancement which incorporates a random mechanism at each boosting step showing an improvement in performance and speed in generating the ensemble. ada is an R package that implements three popular variants of boosting, together with a version of stochastic gradient boosting. In addition, useful plots for data analytic purposes are provided along with an extension to the multi-class case. The algorithms are illustrated with synthetic and real data sets.
