Edwards D
Acad Radiol . 2013 Jun; 20(7):908-14. PMID: 23747155
Rationale And Objectives: Traditional two-class receiver operating characteristic (ROC) analysis is inadequate for the complete evaluation of observer performance in tasks with more than two classes. Materials And Methods: Here,...

Edwards D, Metz C
J Math Psychol . 2012 Nov; 56(4):256-273. PMID: 23162165
Although a fully general extension of ROC analysis to classification tasks with more than two classes has yet to be developed, the potential benefits to be gained from a practical...

MacDermed D, Khodarev N, Pitroda S, Edwards D, Pelizzari C, Huang L, et al.
BMC Med Genomics . 2010 May; 3:16. PMID: 20459602
Background: MUC1 protein is highly expressed in lung cancer. The cytoplasmic domain of MUC1 (MUC1-CD) induces tumorigenesis and resistance to DNA-damaging agents. We characterized MUC1-CD-induced transcriptional changes and examined their...

Edwards D, Metz C
IEEE Trans Med Imaging . 2007 Oct; 26(10):1345-56. PMID: 17948725
We have shown previously that an N-class ideal observer achieves the optimal receiver operating characteristic (ROC) hypersurface in a Neyman-Pearson sense. Due to the inherent complexity of evaluating observer performance...

Edwards D, Metz C
IEEE Trans Med Imaging . 2005 Dec; 24(12):1566-73. PMID: 16350917
We are attempting to develop expressions for the coordinates of points on the three-class ideal observer's receiver operating characteristic (ROC) hypersurface as functions of the set of decision criteria used...

Edwards D, Metz C, Nishikawa R
IEEE Trans Med Imaging . 2005 Mar; 24(3):293-9. PMID: 15754980
We express the performance of the N-class "guessing" observer in terms of the N2-N conditional probabilities which make up an N-class receiver operating characteristic (ROC) space, in a formulation in...
7.
Edwards D, Metz C, Kupinski M
IEEE Trans Med Imaging . 2004 Jul; 23(7):891-5. PMID: 15250641
The likelihood ratio, or ideal observer, decision rule is known to be optimal for two-class classification tasks in the sense that it maximizes expected utility (or, equivalently, minimizes the Bayes...

Edwards D, Lan L, Metz C, Giger M, Nishikawa R
Med Phys . 2004 Feb; 31(1):81-90. PMID: 14761024
We are using Bayesian artificial neural networks (BANNs) to classify mammographic masses in schemes for computer-aided diagnosis, and we are extending this methodology to a three-class classification task. We investigated...

Edwards D, Kupinski M, Metz C, Nishikawa R
Med Phys . 2003 Jan; 29(12):2861-70. PMID: 12512721
We have developed a model for FROC curve fitting that relates the observer's FROC performance not to the ROC performance that would be obtained if the observer's responses were scored...
