Preferential Pliable Index Coding
Daniel Byrne, Lawrence Ong, Parastoo Sadeghi +1
We propose and study a variant of pliable index coding (PICOD) where receivers have preferences for their unknown messages and give each unknown message a preference ranking. We ca…
Vertical Federated Learning: Taxonomies, Threats, and Prospects
Qun Li, Chandra Thapa, Lawrence Ong +5
Federated learning (FL) is the most popular distributed machine learning technique. FL allows machine-learning models to be trained without acquiring raw data to a single point for…
Raptor Codes for Higher-Order Modulation Using a Multi-Edge Framework
Sachini Jayasooriya, Mahyar Shirvanimoghaddam, Lawrence Ong +1
In this paper, we represent Raptor codes as multi-edge type low-density parity-check (MET-LDPC) codes, which gives a general framework to design them for higher-order modulation us…
The DoF Region of the Three-Receiver MIMO Broadcast Channel with Side Information and Its Relation to Index Coding Capacity
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
We consider the three-receiver Gaussian multiple-input multiple-output (MIMO) broadcast channel with an arbitrary number of antennas at each of the transmitter and the receivers. W…
The Finite Field Multi-Way Relay Channel with Correlated Sources: Beyond Three Users
Lawrence Ong, Roy Timo, Sarah J. Johnson
The multi-way relay channel (MWRC) models cooperative communication networks in which many users exchange messages via a relay. In this paper, we consider the finite field MWRC wit…
Optimal Index Codes for a Class of Multicast Networks with Receiver Side Information
Lawrence Ong, Chin Keong Ho
This paper studies a special class of multicast index coding problems where a sender transmits messages to multiple receivers, each with some side information. Here, each receiver…
