Parsimonious downgrading and decision trees applied to the inference problem
LiWu Chang,Ira S. Moskowitz +1 more
TL;DR: This new paradigm has two main parts: the application of decision tree analysis to the inference problem, and the concept of parsimonious downgrading, which includes a new thermodynamically motivated way of dealing with the deduction of inference rules from partial data.
Proceedings ArticleDOI
A new paradigm hidden in steganography
TL;DR: It is discussed how steganography, in contrast to similar disciplines, requires a new paradigm based upon discontinuities and the absence of noise as a detection deterrent.
Proceedings ArticleDOI
Capacity is the wrong paradigm
TL;DR: A new paradigm called "capability" is proposed which gauges the effectiveness of a steganographic method and includes payload carrying ability, detectability, and robustness components.
Book ChapterDOI
An Integrated Framework for Database Privacy Protection
LiWu Chang,Ira S. Moskowitz +1 more
TL;DR: This paper presents a framework to assist in the formal analysis of the database inference problem, based on an association network which is composed of a similarity measure and a Bayesian network model.
Book ChapterDOI
A Study of Inference Problems in Distributed Databases
LiWu Chang,Ira S. Moskowitz +1 more
TL;DR: This paper describes a framework and approach to address the inference problem for distributed databases and outlines a strategy to address this problem in the coming years.
