Iowa State University Electrical and Computer Engineering Professor Aditya Ramamoorthy gave a keynote talk at the 2018 Australian Communication Theory Workshop at the University of Newcastle Jan. 31 to Feb. 2, 2018. This workshop, held annually, brings together Australian researchers in the areas of telecommunications, signal processing, coding and information theory. The workshop featured three keynote talks, one of them by Ramamoorthy.
“I was invited by the organizers to deliver the keynote talk, which was very well received,” he said.
Ramamoorthy’s talk, entitled “Combinatorial Designs for Distributed Storage, Caching and Computation,” demonstrated that combinatorial designs allow for the design of efficient large scale distributed storage systems, including the technique of coded caching.
“We will show that designs can be used to construct a family of directed acyclic networks that have several interesting properties,” he wrote in the seminar’s abstract. “In particular, our work shows that the computation rate of such networks depends significantly on the source alphabets. This is in stark contrast with multiple unicast networks where the rate is independent of the source alphabet.”
Beyond delivering a keynote address, Ramamoorthy gained other positive experiences from the conference.
“The workshop allowed for ample opportunities to network with Australian researchers,” he said. “I was able to have several interesting discussions, which will hopefully lead to collaborative work in the future.”
