Disclosure-Limited Data Dissemination

Journal of the American Statistical Association, 1986
Abstract Statistical agencies use a variety of disclosure control policies with ad hoc justification in disseminating data. The issues involved are clarified here by showing that several of these policies are special cases of a general disclosure-limiting (DL) approach based on predictive distributions and uncertainty functions.

Image reconstruction from limited Fourier data

Journal of the Optical Society of America A, 2006
We consider the problem of reconstructing a function f with bounded support S from finitely many values of its Fourier transform F. Although f cannot be band limited since it has bounded support, it is typically the case that f can be modeled as the restriction to S of a sigma-band-limited function, say g.

Exploiting limited data for parsing

2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS), 2014
Data sparsity issues are extremely severe for parser due to the flexibility of tree structures. Many tags and productions appears a little, nevertheless, they are crucial for the parse disambiguation where it occurs. Besides, when a common tag somewhat regularly occurs in a non-canonical position, its distribution is usually distinct. In this paper, we

Limitations of Data on Fluid Intake

Journal of the American College of Nutrition, 2007
The Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate, provided extensive tables of data on total water intake, water intake from beverages and water intake from foods; however, very little information was provided about the specific details of these analyses.

Limits of Data Value Predictability

International Journal of Parallel Programming, 1999
The predictability of data values is studied at a fundamental level. Two basic predictor models are defined: Computational predictors perform an operation on previous values to yield predicted next values. Examples we study are stride value prediction and last value prediction; Context-Based predictors match recent value history (context) with previous

Querying Data under Access Limitations

2008 IEEE 24th International Conference on Data Engineering, 2008
Data sources on the web are often accessible through web interfaces that present them as relational tables, but require certain attributes to be mandatorily selected, e.g., via a web form. In a scenario where we integrate a set of such sources, and we pose queries over them, the values needed to access a source may have to be retrieved from other ...
