Bayesian networks are a powerful probabilistic representation, and their use for classification has received considerable attention. However, they tend to perform poorly when learned in the standard way. This is attributable to a mismatch between the objective function used (likelihood or a function thereof) and the goal of classification (maximizing(More)
Preface During the 1996-97 academic year, Phillip Griffiths and Robert Bryant conducted a seminar at the Institute for Advanced Study in Princeton, NJ, outlining their recent work (with Lucas Hsu) on a geometric approach to the calculus of variations in several variables. The present work is an outgrowth of that project; it includes all of the material(More)
Second trimester abortion is associated with higher rates of complications compared to first trimester abortion. Dilatation and evacuation (D&E) and medical induction using misoprostol alone or a combination of mifepristone and misoprostol are the methods most commonly used for later abortion in developed countries, yet little research has directly compared(More)

OBJECTIVE To estimate the effectiveness and acceptability of telemedicine provision of early medical abortion compared with provision with a face-to-face physician visit at a Planned Parenthood affiliate in Iowa. METHODS Between November 2008 and October 2009, we conducted a prospective cohort study of women obtaining medical abortion by telemedicine or(More)
In Latin America, where abortion is almost universally legally restricted, medical abortion, especially with misoprostol alone, is increasingly being used, often with the tablets obtained from a pharmacy. We carried out in-depth interviews with 49 women who had had a medical abortion under clinical supervision in rural and urban settings in Mexico,(More)
The growth of data-mining applications such as classification and clustering has shown the need for machine learning algorithms to be applied to large scale data. In this paper we present the comparison of different classification techniques using Waikato Environment for Knowledge Analysis or in short, WEKA. WEKA is open source software which consists of a(More)
Mifepristone medical abortion has been a valuable addition to the reproductive health options of women. Aspects of its provision have however sometimes limited its accessibility and use. This article summarizes existing evidence for simplifying the provision of medical abortion and thus increasing its availability. We identify three ways through which(More)
BACKGROUND Requiring a follow-up visit with ultrasound evaluation to confirm completion after medication abortion can be a barrier to providing the service. STUDY DESIGN The PubMed (including MEDLINE), Cochrane Central Register of Controlled Trials and POPLINE databases were systematically searched in October and November 2009 for studies related to(More)
OBJECTIVE We conducted a systematic review to examine the prevalence of minor and major complications following first-trimester aspiration abortion requiring medical or surgical intervention. STUDY DESIGN We searched PubMed, Cumulative Index to Nursing and Allied Health Literature, Scopus and the Cochrane Library for articles published between 1980 and(More)
