Assisted Common Information with an Application to Secure Two-Party Sampling
Assisted Common Information Secure Two-Party Sampling Information Theory
2012/6/25
In this paper we generalize the notion of common information of two dependent variables introduced by G\'acs & K\"orner. They defined common information as the largest entropy rate of a common random ...
Sumset and Inverse Sumset Inequalities for Differential Entropy and Mutual Information
Shannon entropy differential entropy sumset bounds inequalities submodularity data processing mutual information
2012/6/19
The sumset and inverse sumset theories of Freiman, Pl\"{u}nnecke and Ruzsa, give bounds connecting the cardinality of the sumset $A+B=\{a+b\;;\;a\in A,\,b\in B\}$ of two discrete sets $A,B$, to the ca...
Information Transmission using the Nonlinear Fourier Transform, Part II: Numerical Methods
Fiber-optic communications forward nonlinear Fourier transform Zakharov-Shabat spectral problem numerical methods
2012/4/23
In this paper, numerical methods are suggested to compute the discrete and the continuous spectrum of a signal with respect to the Zakharov-Shabat system, a Lax operator underlying numerous integrable...
On Dispersions of Discrete Memoryless Channels with Noncausal State Information at the Encoder
Dispersions of Discrete Memoryless Channels Noncausal State Information Encoder Information Theory
2012/4/18
In this paper, we study the finite blocklength limits of state-dependent discrete memoryless channels where the discrete memoryless state is known noncausally at the encoder. For the point-to-point ca...
In this work we analyze principle component analysis (PCA) as a deterministic input-output system. We show that the relative information loss induced by reducing the dimensionality of the data after p...
On The Achievable Rate Region of a New Wiretap Channel With Side Information
Equivocation rate secrecy capacity side information wiretap channel perfect secrecy
2012/4/17
A new applicable wiretap channel with separated side information is considered here which consist of a sender, a legitimate receiver and a wiretapper. In the considered scenario, the links from the tr...
Information-theoretically Secure Regenerating Codes for Distributed Storage
Information-theoretically Secure Regenerating Codes Distributed Storage
2011/9/21
Abstract: Regenerating codes are a class of codes for distributed storage networks that provide reliability and availability of data, and also perform efficient node repair. Another important aspect o...
Non-equilibrium Information Envelopes and the Capacity-Delay-Error-Tradeoff of Source Coding
Non-equilibrium Information Envelopes Capacity-Delay-Error-Tradeoff Source Coding Information Theory
2011/10/8
Abstract: This paper develops an envelope-based approach to establish a link between information and queueing theory. Unlike classical, equilibrium information theory, information envelopes focus on t...
An Introductory Review of Information Theory in the Context of Computational Neuroscience
Introductory Review of Information Theory the Context of Computational Neuroscience Information Theory
2011/9/9
Abstract: This paper introduces several fundamental concepts in information theory from the perspective of their origins in engineering. Understanding such concepts is important in neuroscience for tw...
Blending Bayesian and frequentist methods according to the precision of prior information with an application to hypothesis testing
blended inference confidence distribution confidence posterior hybrid inference maximum entropy
2011/9/30
Abstract: The following zero-sum game between nature and a statistician blends Bayesian methods with frequentist methods such as p-values and confidence intervals. Nature chooses a posterior distribut...
An Interpretation of the Moore-Penrose Generalized Inverse of a Singular Fisher Information Matrix
Cramer-Rao bound constrained parameters singular Fisher information matrix
2011/9/1
Abstract: An interpretation of the Moore-Penrose generalized inverse of a singular Fisher information matrix (FIM) is presented in this paper, from the perspective of Cramer-Rao bound (CRB). CRB is a ...

Additive functional Entropy Singularities Natural Border Problem Invariant
2011/8/31
Abstract: The paper introduces the recent results related to an entropy functional on trajectories of a controlled diffusion process, and the information path functional (IPF), analyzing their connect...
On the information-theoretic structure of distributed measurements
information-theoretic structure Information Theory Category Theory
2011/8/26
Abstract: The internal structure of a measuring device, which depends on what its components are and how they are organized, determines how it categorizes its inputs. This paper presents a geometric a...
