  • Zhu, Xuwen (University of Alabama Libraries, 2016)
    Cluster analysis performs unsupervised partition of heterogeneous data. It has applications in almost all fields of study. Model-based clustering is one of the most popular clustering methods these days due to its flexibility ...
  • Ballard, Marcus Alan (University of Alabama Libraries, 2018)
    A network consists of vertices and edges that connect the vertices. A network is clustered by assigning each of the N vertices to one of k groups, usually in order to optimize a given objective function. This dissertation ...
  • Xu, Jie (University of Alabama Libraries, 2013)
    Ensemble models, such as bagging (Breiman, 1996), random forests (Breiman, 2001a), and boosting (Freund and Schapire, 1997), have better predictive accuracy than single classifiers. These ensembles typically consist of ...
  • Martinez Cid, Waldyn Gerardo (University of Alabama Libraries, 2012)
    Ensemble methods, such as bagging (Breiman, 1996), boosting (Freund and Schapire, 1997) and random forests (Breiman, 2001) combine a large number of classifiers through (weighted) voting to produce strong classifiers. To ...
  • Neve, Benjamin V. (University of Alabama Libraries, 2011)
    This work considers three different non-traditional supply chain structures with similar demand and replenishment parameters, and similar solution techniques. In the first article, we develop an inventory model that addresses ...
  • Tribble, Larry (University of Alabama Libraries, 2016)
    The question of the value contribution of Information Technology (IT) to the firm is a continuing concern in Management Information Systems (MIS) research. While firms make significant investments in IT resources and ...
  • Li, Rong (University of Alabama Libraries, 2012)
    Routing related costs constitute a significant portion of the overall logistics costs in most service industries. Private companies are continuously striving to reduce their vehicle routing costs to maintain a better ...
  • Palmer, Nathan Curtis (University of Alabama Libraries, 2009)
    It is important for every company to minimize its costs. This includes labor costs. We develop mathematical models that allow a company to minimize its labor costs by deciding from where to hire workers and the amount that ...
