The Rough Topology for Numerical Data
Uğur Yiğit
In this paper, we generalize the rough topology and the core to numerical data by classifying objects in terms of the attribute values. A new approach to finding the core for numer…
Variational Information Bottleneck for Unsupervised Clustering: Deep Gaussian Mixture Embedding
Yigit Ugur, George Arvanitakis, Abdellatif Zaidi
In this paper, we develop an unsupervised generative clustering framework that combines the Variational Information Bottleneck and the Gaussian Mixture Model. Specifically, in our…
Vector Gaussian CEO Problem Under Logarithmic Loss
Yigit Ugur, Inaki Estella Aguerri, Abdellatif Zaidi
In this paper, we study the vector Gaussian Chief Executive Officer (CEO) problem under logarithmic loss distortion measure. Specifically, agents observe independently c…
Vector Gaussian CEO Problem Under Logarithmic Loss and Applications
Yigit Ugur, Inaki Estella Aguerri, Abdellatif Zaidi
We study the vector Gaussian Chief Executive Officer (CEO) problem under logarithmic loss distortion measure. Specifically, agents observe independently corrupted Gaussi…
A Generalization of Blahut-Arimoto Algorithm to Compute Rate-Distortion Regions of Multiterminal Source Coding Under Logarithmic Loss
Yigit Ugur, Inaki Estella Aguerri, Abdellatif Zaidi
In this paper, we present iterative algorithms that numerically compute the rate-distortion regions of two problems: the two-encoder multiterminal source coding problem and the Chi…
Reducing MIMO Detection Complexity via Hierarchical Modulation
Yigit Ugur, Ali Ozgur Yilmaz
This work considers multiple-input multiple-output (MIMO) communication systems using hierarchical modulation. A disadvantage of the maximum-likelihood (ML) MIMO detector is that c…
Cloud Radio Access Networks with Coded Caching
Yigit Ugur, Zohaib Hassan Awan, Aydin Sezgin
A cloud radio access network (C-RAN) is considered as a candidate to meet the expectations of higher data rate de- mands in wireless networks. In C-RAN, low energy base stations (B…
