چکیده
Figure 1 illustrates the interaction between a client and a database server hosting privacysensitive data, e.g., data about people’s health conditions. Di↵erential privacy prevents revealing the identity of an individual by adding noise to the query results, s.t. information about any one particular individual remain hidden. For example, a client won’t be able to tell whether Chris (or any other individual) is sick or not, even if it can query about the number of sick people. A formal definition of di↵erential privacy is given in Section 3.

Numerical Solution of fuzzy differential equations of nth-order by Adams-Bashforth method
So far, many methods have been presented to solve the rst-order di erential equations. But, not many studies have been conducted for numerical solution of high-order fuzzy di erential equations. In this research, First, the equation by reducing time, we transform the rst-order equation. Then we have applied Adams-Bashforth multi-step methods for the initial approximation of one order di erentia...
متن کاملLearning in a Large Function Space: Privacy-Preserving Mechanisms for SVM Learning
Several recent studies in privacy-preserving learning have considered the trade-o between utility or risk and the level of di erential privacy guaranteed by mechanisms for statistical query processing. In this paper we study this trade-o in private Support Vector Machine (SVM) learning. We present two e cient mechanisms, one for the case of nite-dimensional feature mappings and one for potentia...
متن کاملA Framework for Adaptive Di erential
Di erential privacy is a widely studied theory for analyzing sensitive data with a strong privacy guarantee— any change in an individual’s data can have only a small statistical e ect on the result—and a growing number of programming languages now support di erentially private data analysis. A common shortcoming of these languages is poor support for adaptivity. In practice, a data analyst rare...
متن کاملAn algorithm for computing the rst homology groups of CDGAs with linear di erential
We design here a primary platform for computing the basic homological information of Commutative Di erential Graded Algebras (brie y, CDGAs), endowed with linear di erential. All the algorithms have been implemented in the framework settled by Mathematica, so that we can take advantage of the use of symbolic computation and many other powerful tools this system provides. Working in the context ...
متن کاملEnd-to-End Differentially-Private Parameter Tuning in Spatial Histograms
ABSTRACT Dierentially-private histograms have emerged as a key tool for location privacy. While past mechanisms have included theoretical & experimental analysis, it has recently been observed that much of the existing literature does not fully provide dierential privacy. e missing component, private parameter tuning, is necessary for rigorous evaluation of these mechanisms. Instead works fr...
