Functional Dependence and Analytic Functions [PDF]
Canadian Mathematical Bulletin, 1979 AbstractWithout appealing to the Cauchy theorem or its corollaries, it is proved that the real and imaginary parts of a non-constant complex-valued analytic function of several complex variables are functionally independent. This unifies and generalizes some results sporadically treated in standard treatises on function theory.

Wide-coverage deep statistical parsing using automatic dependency structure annotation [PDF]
, 2008 A number of researchers (Lin 1995; Carroll, Briscoe, and Sanfilippo 1998; Carroll et al. 2002; Clark and Hockenmaier 2002; King et al. 2003; Preiss 2003; Kaplan et al. 2004;Miyao and Tsujii 2004) have convincingly argued for the use of dependency (rather

Functional Dependencies with null Markers [PDF]
The Computer Journal, 2014 Functional dependencies are an integral part of database design. However, they are only defined when we exclude null markers. Yet we commonly use null markers in practice. To bridge this gap between theory and practice, researchers have proposed definitions of functional dependencies over relations with null markers.

Dependent Functional Data [PDF]
ISRN Probability and Statistics, 2012 This paper reviews recent research on dependent functional data. After providing an introduction to functional data analysis, we focus on two types of dependent functional data structures: time series of curves and spatially distributed curves. We review statistical models, inferential methodology, and possible extensions.

Dependency-based automatic evaluation for machine translation [PDF]
, 2007 We present a novel method for evaluating the output of Machine Translation (MT), based on comparing the dependency structures of the translation and reference rather than their surface string forms.

How to Mine Information from Each Instance to Extract an Abbreviated and Credible Logical Rule
Entropy, 2014 Decision trees are particularly promising in symbolic representation and reasoning due to their comprehensible nature, which resembles the hierarchical process of human decision making.

Bounds for Functions of Dependent Risks [PDF]
Finance and Stochastics, 2006 For an \(n\)-variate real function \(\psi\) and a random vector \(X:=(X_1,\dots,X_n)\) the problem of finding the best possible lower bound on the distribution function of \(\psi(X)\) is studied when the marginal distributions of the individual risks \(X_i\) are given and the structure of dependence of \(X\) is partially or completely unknown.

Dependency-based n-gram models for general purpose sentence realisation [PDF]
, 2008 We present dependency-based n-gram models for general-purpose, widecoverage, probabilistic sentence realisation. Our method linearises unordered dependencies in input representations directly rather than via the application of grammar rules, as in ...

Discovering Graph Functional Dependencies [PDF]
ACM Transactions on Database Systems, 2018 This article studies discovery of Graph Functional Dependencies (GFDs), a class of functional dependencies defined on graphs. We investigate the fixed-parameter tractability of three fundamental problems related to GFD discovery. We show that the implication and satisfiability problems are fixed-parameter tractable, but the validation problem is co-W[1]

Mining Conditional Functional Dependency Rules on Big Data
Big Data Mining and Analytics, 2020 Current Conditional Functional Dependency (CFD) discovery algorithms always need a well-prepared training dataset. This condition makes them difficult to apply on large and low-quality datasets.
