Ambiguity measure feature‐selection algorithm

Journal of the American Society for Information Science and Technology, 2009
AbstractWith the increasing number of digital documents, the ability to automatically classify those documents both efficiently and accurately is becoming more critical and difficult. One of the major problems in text classification is the high dimensionality of feature space.

Remarks on “Measuring Ambiguity in the Evidence Theory”

IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2008
In a recent paper, a functional AM (ambiguity measure) is introduced and an attempt is made to show that this functional qualifies as a measure of total aggregated uncertainty in the Dempster-Shafer theory. We show that this attempt fails due to a particular error in the proof of one of the principal theorems in the paper.

“Ambiguity” and scientometric measurement: A dissenting view

Journal of the American Society for Information Science and Technology, 2001
AbstractAbe Bookstein has long been a persuasive advocate of the central role of the classical Lotka‐Bradford‐Zipf “laws” in bibliometrics and, subsequently, scientometrics and informetrics. In a series of often‐quoted papers (Bookstein, 1977, 1990a, 1990b, 1997), he has sought to demonstrate that “Lotka‐type” laws have a unique resilience to various ...

On the study of ambiguity and the trade-off between measures and ambiguity in insertion–deletion languages

Nano Communication Networks, 2011
Abstract Gene insertion and deletion are the operations that occur commonly in DNA processing and RNA editing. Based on these operations, a computing model has been formulated in formal language theory known as insertion–deletion systems. In this paper we study about ambiguity issues of these systems.

Ambiguous Measurements Multitarget Tracking with Random Sets

2008 International Conference on Computational Intelligence and Security, 2008
In this paper, we represent multi-target state and ambiguous measurement as random sets, use ambiguous likelihood to fuse ambiguous data for tracking multiple targets, and we implement multi-target tracking with probability hypothesis density (PHD) particle filter.

An Effectiveness Measure for Ambiguous and Underspecified Queries

2009
Building upon simple models of user needs and behavior, we propose a new measure of novelty and diversity for information retrieval evaluation. We combine ideas from three recently proposed effectiveness measures in an attempt to achieve a balance between the complexity of genuine users needs and the simplicity required for feasible evaluation.
