The bias of sequential testing in predictive coding

Text classifiers (or predictive coders) are in general trained iteratively, with training data added until acceptable effectiveness is achieved. Some method of measuring or estimating effectiveess is required—or, more precisely, of predicting effectiveness on the remainder of the collection. The simplest way of measuring classifier effectiveness is with a random sample of documents, from which […] → Read More: The bias of sequential testing in predictive coding

Non-authoritative relevance coding degrades classifier accuracy

There has been considerable attention paid to the high level of disagreement between assessors on the relevance of documents, not least on this blog. This level of disagreement has been cited to argue in favour of the use of automated text analytics (or predictive coding) in e-discovery: not only do humans make mistakes, but they […] → Read More: Non-authoritative relevance coding degrades classifier accuracy

A 3D Pottery Content Based Retrieval Benchmark Dataset

About the 3D Pottery Benchmark The existence of benchmark data sets is essential in order to perform the evaluation and the comparison of content based retrieval methods. Although, no standard benchmark is available for 3D data shape matching there is… → Read More: A 3D Pottery Content Based Retrieval Benchmark Dataset

In Defense of the Skeuomorph, or Maybe Not…

Jony Ive is a fantastic designer. As a rule, his vision for a device sets the trend for that entire class of devices. Apparently, Jony Ive hates skeuomorphic design elements. Skeuomorphs are those sometimes corny bits of realism some designers add to user interfaces. These design elements reference an application’s analog embodiment. Apple’s desktop and mobile interfaces […] → Read More: In Defense of the Skeuomorph, or Maybe Not…

Peer-review debate should include software

Article from http://www.researchinformation.info/news/news_story.php?news_id=1268 It’s not often that coding errors make the news. But back in April one particular slip-up with formulae on an Excel spreadsheet caused worldwide repercussions. It emerg… → Read More: Peer-review debate should include software
