Total review cost of training selection methods

My previous post described in some detail the conditions of finite population annotation that apply to e-discovery. To summarize, what we care about (or at least should care about) is not maximizing classifier accuracy in itself, but minimizing the total cost of achieving a target level of recall. The predominant cost in the review stage […] → Read More: Total review cost of training selection methods

LoCo: a framework for indoor location of mobile devices

Last year, we initiated the LoCo project on indoor location.  The LoCo page has more information, but our central goal is to provide highly accurate, room-level location information to enable indoor location services to complement the location services built on GPS outdoors. Last week, we presented our initial results on the work at Ubicomp 2014.  In […] → Read More: LoCo: a framework for indoor location of mobile devices

Finite population protocols and selection training methods

In a previous post, I compared three methods of selecting training examples for predictive coding—random, uncertainty and relevance. The methods were compared on their efficiency in improving the accuracy of a text classifier; that is, the number of training documents required to achieve a certain level of accuracy (or, conversely, the level of accuracy achieved […] → Read More: Finite population protocols and selection training methods

Gesture Viewport: Interacting with Media Content Using Finger Gestures on Any Surface

At ICME 2014 in Chengdu, China, we presented a technical demo called “Gesture Viewport,” which is a projector-camera system that enables finger gesture interactions with media content on any surface. In the demo, we used a portable Pico projector to project a viewport widget (along with its content) onto a desktop and a Logitech webcam […] → Read More: Gesture Viewport: Interacting with Media Content Using Finger Gestures on Any Surface
