Hierarchical Forecast Reconciliation on Networks: A Network Flow Optimization Formulation
Charupriya Sharma, Iñaki Estella Aguerri, Daniel Guimarans
Hierarchical forecasting with reconciliation requires forecasting values of a hierarchy (e.g.~customer demand in a state and district), such that forecast values are linked (e.g.~…
Beyond Transmitting Bits: Context, Semantics, and Task-Oriented Communications
Deniz Gunduz, Zhijin Qin, Inaki Estella Aguerri +5
Communication systems to date primarily aim at reliably communicating bit sequences. Such an approach provides efficient engineering designs that are agnostic to the meanings of th…
Optimal Rate-Exponent Region for a Class of Hypothesis Testing Against Conditional Independence Problems
Abdellatif Zaidi, Inaki Estella Aguerri
We study a class of distributed hypothesis testing against conditional independence problems. Under the criterion that stipulates minimization of the Type II error rate subject to…
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…
Distributed Variational Representation Learning
Inaki Estella Aguerri, Abdellatif Zaidi
The problem of distributed representation learning is one in which multiple sources of information are processed separately so as to learn as much information as p…
Distributed Information Bottleneck Method for Discrete and Gaussian Sources
Inaki Estella Aguerri, Abdellatif Zaidi
We study the problem of distributed information bottleneck, in which multiple encoders separately compress their observations in a manner such that, collectively, the compressed si…
On the Capacity of Cloud Radio Access Networks with Oblivious Relaying
Inaki Estella Aguerri, Abdellatif Zaidi, Giuseppe Caire +1
We study the transmission over a network in which users send information to a remote destination through relay nodes that are connected to the destination via finite-capacity error…
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…
On the Capacity of Cloud Radio Access Networks with Oblivious Relaying
Inaki Estella Aguerri, Abdellatif Zaidi, Giuseppe Caire +1
We study the transmission over a network in which users send information to a remote destination through relay nodes that are connected to the destination via finite-capacity error…
In-network Compression for Multiterminal Cascade MIMO Systems
Inaki Estella Aguerri, Abdellatif Zaidi
We study the problem of receive beamforming in uplink cascade multiple-input multiple-output (MIMO) systems as an instance of that of cascade multiterminal source coding for lossy…
Lossy Compression for Compute-and-Forward in Limited Backhaul Uplink Multicell Processing
Iñaki Estella Aguerri, Abdellatif Zaidi
We study the transmission over a cloud radio access network in which multiple base stations (BS) are connected to a central processor (CP) via finite-capacity backhaul links. We pr…
Distortion Exponent in MIMO Fading Channels with Time-Varying Source Side Information
Iñaki Estella Aguerri, Deniz Gündüz
Transmission of a Gaussian source over a time-varying multiple-input multiple-output (MIMO) channel is studied under strict delay constraints. Availability of a correlated side inf…
Capacity of a Class of State-Dependent Orthogonal Relay Channels
Iñaki Estella Aguerri, Deniz Gündüz
The class of orthogonal relay channels in which the orthogonal channels connecting the source terminal to the relay and the destination, and the relay to the destination, depend on…
Joint Source-Channel Coding with Time-Varying Channel and Side-Information
Iñaki Estella Aguerri, Deniz Gündüz
Transmission of a Gaussian source over a time-varying Gaussian channel is studied in the presence of time-varying correlated side information at the receiver. A block fading model…
