Author: Yoram Reich","Steven J. Fenves Source: [original](http://openml.org/d/19) - Please cite: Pittsburgh bridges This version is derived from version 2 (the discretized version) by removing all instances with missing values in the last (target) attribute. The bridges dataset is originally not a classification dataset, put is used so extensively in the literature, using the last attribute as the target attribute. However, this attribute has missing values, which may lead to confusing benchmarking result. Therefore, these instances have been removed. Sources: -- Yoram Reich and Steven J. Fenves Department of Civil Engineering and Engineering Design Research Center Carnegie Mellon University Pittsburgh, PA 15213 Compiled from various sources. -- Date: 1 August 1990 Attribute Information: The type field state whether a property is continuous/integer (c) or nominal (n). For properties with c,n type, the range of continuous numbers is given first and the possible values of the nominal follow the semi-colon. name type possible values comments ------------------------------------------------------------------------ 1.
