Accept on Zero A statistical sampling procedure (an acceptance sampling procedure) that draws a random sample of objects from a population and checks each one to determine whether it is a defect. If none of the objects in the sample is found to be defective, then we can conclude with a specifiable level of confidence that there were no more than a specifiable proportion of defects in the original population. Finding zero defects in the sample does not mean that there were zero defects in the population, only that there were no more than a specifiable percentage. One application of this procedure in eDiscovery is to draw a random sample from the population of documents determined by the review to be nonresponsive. The size of the sample is determined by your specified confidence level and by the maximum acceptable percentage of responsive documents that were not retrieved. If none of the documents in the sample is found to be responsive, then we can say with confidence X% that there were no more than Y% responsive documents left behind.

Accept on Zero Error A technique in which the training of a Machine Learning method is gauged by taking a Sample after each training step, and deeming the training process complete when the learning method codes a Sample with 0% Error (i.e., 100% Accuracy). © 2016 EDRM LLC 1 EDRM Glossary http://www.edrm.net/resources/glossaries/glossary Source: Maura R. Grossman and Gordon V. Cormack, EDRM page & The Grossman- Cormack Glossary of Technology-Assisted Review, with Foreword by John M. Facciola, U.S. Magistrate Judge, 2013 Fed. Cts. L. Rev. 7 (January 2013). Accuracy The fraction of Documents that are correctly coded by a search or review effort. Note that Accuracy + Error = 100%, and that Accuracy = 100% – Error. While high Accuracy is commonly advanced as evidence of an effective search or review effort, its use can be misleading because it is heavily influenced by Prevalence. Consider, for example, a Document Population containing one million Documents, of which ten thousand (or 1%) are Relevant. A search or review effort that identified 100% of the Documents as Not Relevant and therefore, found none of the Relevant Documents, would have 99% Accuracy, belying the failure of that search or review effort.
