How to Shrink Big Data

Jelani Nelson, a computer scientist at the University of California, Berkeley, expands the theoretical possibilities for low-memory streaming algorithms. He’s discovered the best procedures for answering on-the-fly questions like “How many different users are there?” (known as the distinct elements problem) and “What are the trending search terms right now?” (the frequent items problem). Nelson’s algorithms often use a technique called sketching, which compresses big data sets into smaller components that can be stored using less memory and analyzed quickly.

No wonder he looks so familiar, I watched him in one of Harvard's video class!

[JohannSuarez]

He's the dude from that Harvard class!

I just took Jelani's algorithm course in Berkeley, it was simply amazing. I learned so much stuff and the guy was just incredible at explaining these huge algorithms and how they work. Best professor ever! huge fan of Jelani Nelson's work

Amazing. Jelani is contributing so much to the community! These are the real heroes. Thanks Quanta for showcasing his work 💙💙

Simply he is genius and hard working man... he helped and inspired many peoples' ...God bless you,

I like the fact he kept the two most important books in Computer Science, Introduction to Algorithms by CLRS and C++ by Schildt.

Still waiting for the 9 mb version of cyberpunk 2077

[maxvelazquez]

This guy is just so intelligent and hardworking and I admire him SO MUCH

My man here is using ubuntu on a thinkpad and fucking with memory space. I might just have a new hero.

Damn, this dude is only 36 years old and he sounds like he has 50+ years experiance in his field (I've watched some other videos of him as well)

[mulugetakejela]

This guy doesn’t age at all. He looks exactly like he did 9 years ago. Genius too.

2:04 the definite answer to "whether or not HTML is a programming language"

[marco.nascimento]

I've watched some of his classes at Harvard's channel, amazing professor

[flickmew]

this is the briliant J Cole dude, his lessons are incredible

[nirbhaysaluja]

what is that green book next to the c++ on 0:17?

[Vikash_Art]

I m gonna add those two books in my Library folder

[donjohn]

I have no idea what this man is talking about; I'm only here because I've watched this man in a Harvard course lmao

[georgecostanza]

I watch this guy from Harvard and the stuff he does leaves me confused. But intrigued.

[proximacentaur]

It beggars belief that this channel doesn't have more subscribers. Can he fix the YouTube algorithm?

[grandmastergyorogyoro]

Whats the name of the
C++ book .on the tabe please?
