Optimal Neural Compressors for the Rate-Distortion-Perception Tradeoff
Eric Lei, Hamed Hassani, Shirin Saeedi Bidokhti
Recent efforts in neural compression have focused on the rate-distortion-perception (RDP) tradeoff, where the perception constraint ensures the source and reconstruction distributi…
Group Testing with General Correlation Using Hypergraphs
Hesam Nikpey, Saswati Sarkar, Shirin Saeedi Bidokhti
Group testing, a problem with diverse applications across multiple disciplines, traditionally assumes independence across nodes' states. Recent research, however, focuses on real-w…
Approaching Rate-Distortion Limits in Neural Compression with Lattice Transform Coding
Eric Lei, Hamed Hassani, Shirin Saeedi Bidokhti
Neural compression has brought tremendous progress in designing lossy compressors with good rate-distortion (RD) performance at low complexity. Thus far, neural compression design…
On a Relation Between the Rate-Distortion Function and Optimal Transport
Eric Lei, Hamed Hassani, Shirin Saeedi Bidokhti
We discuss a relationship between rate-distortion and optimal transport (OT) theory, even though they seem to be unrelated at first glance. In particular, we show that a function d…
Bounds on the Capacity of the Multiple Access Diamond Channel with Cooperating Base-Stations
Michael Dikshtein, Shirin Saeedi Bidokhti, Shlomo Shamai
A diamond network is considered in which the central processor is connected, via backhaul noiseless links, to multiple conferencing base stations, which communicate with a single u…
Group Testing with Correlation under Edge-Faulty Graphs
Hesam Nikpey, Jungyeol Kim, Xingran Chen +2
In applications of group testing in networks, e.g. identifying individuals who are infected by a disease spread over a network, exploiting correlation among network nodes provides…
Timely Broadcasting in Erasure Networks: Age-Rate Tradeoffs
Xingran Chen, Renpu Liu, Shaochong Wang +1
The interplay between timeliness and rate efficiency is investigated in packet erasure broadcast channels with feedback. A scheduling framework is proposed in which coding actions,…
State-Adaptive Coded Caching for Symmetric Broadcast Channels
Shirin Saeedi Bidokhti, Michèle Wigger, Aylin Yener +1
Coded-caching delivery is considered over a symmetric noisy broadcast channel whose state is unknown at the transmitter during the cache placement phase. In particular, the deliver…
Benefits of Cache Assignment on Degraded Broadcast Channels
Shirin Saeedi Bidokhti, Michele Wigger, Aylin Yener
Degraded K-user broadcast channels (BC) are studied when receivers are facilitated with cache memories. Lower and upper bounds are derived on the capacity-memory tradeoff, i.e., on…
Capacity Bounds on the Downlink of Symmetric, Multi-Relay, Single Receiver C-RAN Networks
Shirin Saeedi Bidokhti, Gerhard Kramer, Shlomo Shamai
The downlink of symmetric Cloud Radio Access Networks (C-RANs) with multiple relays and a single receiver is studied. Lower and upper bounds are derived on the capacity. The lower…
Improved Converses and Gap Results for Coded Caching
Chien-Yi Wang, Shirin Saeedi Bidokhti, Michele Wigger
Improved lower bounds on the average and the worst-case rate-memory tradeoffs for the Maddah-Ali&Niesen coded caching scenario are presented. For any number of users and files and…
Capacity Regions of Two-User Broadcast Erasure Channels with Feedback and Hidden Memory
Michael Heindlmaier, Shirin Saeedi Bidokhti
The two-receiver broadcast packet erasure channel with feedback and memory is studied. Memory is modeled using a finite-state Markov chain representing a channel state. The channel…
On Capacity Regions of Two-Receiver Broadcast Packet Erasure Channels with Feedback and Memory
Michael Heindlmaier, Navid Reyhanian, Shirin Saeedi Bidokhti
The two-receiver broadcast packet erasure channel with feedback and memory is studied. Memory is modeled using a finite-state Markov chain representing a channel state. Outer and i…
Is Non-Unique Decoding Necessary?
Shirin Saeedi Bidokhti, Vinod M. Prabhakaran
In multi-terminal communication systems, signals carrying messages meant for different destinations are often observed together at any given destination receiver. Han and Kobayashi…
