We will be meeting online from 6pm to 8pm.

Guy Royse will be talking about "Understanding Probabilistic Data Structures with 112,092 UFO Sightings"

Guy likes weird stuff—UFOs, Bigfoot, peanut butter and bologna on toast—maybe you do too? As far as the third bullet point, well, that’s how many sightings he has.

Now, if you’re like most developers, you probably have no idea what probabilistic data structures are. In fact, Guy did a super-scientific poll on Twitter and found that out of 119 participants, 58% had never heard of them and 22% had heard the term but nothing more. He wondered what percentage of that 22% heard the term for the first time in the poll. We’re a literal-minded lot at times.

In this talk, we’ll briefly go over some common probabilistic data structures; dive deep into a couple (Bloom Filter, MinHash, and Top-K); and show a running application that makes use of Top-K to analyze the most commonly used words in all 112,092 of his UFO sightings.

When we’re done, you’ll be ready to start using some of these structures in your own applications. And, if you use the UFO data, maybe you’ll discover that the truth really is out there.

This group is only as good as its inputs. Please consider helping out.
