Bilgi kuramı nedir? Nakiboğlu, Barış (2021-10-01) https://sarkac.org/2021/10/bilgi-kurami-nedir/
On the Existence of the Augustin Mean Cheng, Hao-Chung; Nakiboğlu, Barış (2021-01-01) The existence of a unique Augustin mean and its invariance under the Augustin operator are established for arbitrary input distributions with finite Augustin information for channels with countably generated output σ-algeb...
The Sphere Packing Bound for Memoryless Channels Nakiboğlu, Barış (Pleiades Publishing Ltd, 2020-07-01) Sphere packing bounds (SPBs)-with prefactors that are polynomial in the block length-are derived for codes on two families of memoryless channels using Augustin's method: (possibly nonstationary) memoryless channels with (...
Refined Strong Converse for the Constant Composition Codes Cheng, Hao-Chung; Nakiboğlu, Barış (2020-06-01) A strong converse bound for constant composition codes of the form P (n) e ≥ 1-An -0.5(1-E0sc(R,W,p))e-nEsc(R,W,p) is established using the Berry-Esseen theorem through the concepts of Augustin information and Augustin mea...
A simple derivation of the refined sphere packing bound under certain symmetry hypotheses Nakiboğlu, Barış (2020-01-01) A judicious application of the Berry-Esseen theorem via suitable Augustin information measures is demonstrated to be sufficient for deriving the sphere packing bound with a prefactor that is Omega (n(-0.5(1-E'sp)((R)))) fo...
The Sphere Packing Bound for DSPCs with Feedback à la Augustin Nakiboğlu, Barış (Institute of Electrical and Electronics Engineers (IEEE), 2019-11-01) Establishing the sphere packing bound for block codes on the discrete stationary product channels with feedback—which are commonly called the discrete memoryless channels with feedback—was considered to be an open problem ...
The Augustin Capacity and Center Nakiboğlu, Barış (Pleiades Publishing Ltd, 2019-10-01) For any channel, the existence of a unique Augustin mean is established for any positive order and probability mass function on the input set. The Augustin mean is shown to be the unique fixed point of an operator defined ...
A Simple Derivation of the Refined SPB for the Constant Composition Codes Nakiboğlu, Barış (2019-07-01) A judicious application of the Berry-Esseen theorem via the concepts of Augustin information and mean is demonstrated to be sufficient for deriving the sphere packing bound with a prefactor that is Omega(n(-0.5(1-E'sp(R,W,...
The Sphere Packing Bound via Augustin's Method Nakiboğlu, Barış (Institute of Electrical and Electronics Engineers (IEEE), 2019-02-01) A sphere packing bound (SPB) with a prefactor that is polynomial in the block length n is established for codes on a length n product channel W-[1,W- n], assuming that the maximum order 1/2 Renyi capacity among the compone...
The Renyi Capacity and Center Nakiboğlu, Barış (Institute of Electrical and Electronics Engineers (IEEE), 2019-02-01) Renyi's information measures-the Renyi information, mean, capacity, radius, and center-are analyzed relying on the elementary properties of the Renyi divergence and the power means. The van Erven-Harremoes conjecture is pr...
