Jim Keller had a pretty whirlwind week in Rio de Janeiro.
But it wasn’t a sightseeing trip for the Mizzou Electrical Engineering and Computer Science professor. This visit was all business.
Keller gave a keynote presentation, presented on two research papers, was re-elected vice president of publications and participated in a panel discussion at the Institute of Electrical and Electronics Engineers Computational Intelligence Society (IEEE CIS) World Congress on Computational Intelligence WCCI in Brazil in July.
The two papers he presented touched on similar subject matter. “Sequential Possibilistic One-Means Clustering with Dynamic Eta,” was written with graduate student Wenlong Wu and Thomas Runkler, a friend of Keller’s who currently works for Siemens in Munich, Germany. This paper dealt with structuring already complete data sets. The other was written with graduate student Omar Ibrahim and James Bezdek, who taught computer science at various universities, and was titled “Analysis of Streaming Clustering Using an Incremental Validity Index.” It discussed how to structure data sets in real time as new data comes in.
“You have massive amounts of data now coming in, and you just want to say, ‘Are there natural groupings of data?’” Keller explained.
“When people go out on the internet, and they keep track of all those clicks, if you wanted to know if people were interested in the College of Engineering, you’d hope they click the same kind of things, and their streams would all come together. That general stream (of data) is called clustering.”
His keynote address, “Streaming Consciousness on Streaming Clustering,” was given before a sizeable crowd of 1,000-plus. Keller discussed the needs in terms of processing and structuring online streaming data sets in real time in the era of Big Data.
“The motivation for it is the eldercare work that we do,” he said. “We have sensors in people’s apartments, and that data is coming in continuously. And you can’t wait until you get it all, because they’ll be dead. So you need to build the clusters, the model of what’s going on, as the data is coming in.”
He also served on a panel titled “Almost a Century of Lifetime — Lofti Zadeh and the Fuzzy Sets,” a discussion of the life and career of Zadeh, the creator of fuzzy set theory who died in September.
Keller has long been involved in the editing process of IEEE CIS journals in one position or another, and his latest position the last two years was vice president of publications. He earned a second term at WCCI and spent time at several associate editor lunches and committee meetings as part of his position.
“I have always been partial to the publication arm of the society, and I thought I could do some good as VP of pubs,” he said.
