Stochastic Gradient Boosted Decision Trees (GBDT) is one of the most widely used learning algorithms in machine learning today. It is adaptable, easy to interpret, and produces highly accurate models. However, most implementations today are computationally expensive and require all training data to ...

Social networks have become a major focus of research in recent years, initially directed towards static networks but increasingly, towards dynamic ones. In this paper, we investigate how different pre-processing decisions and different network forces such as selection and influence affect the model ...

Hi, everyone. Welcome. I have four super handouts for you
today. If you haven't gotten them yet, feel free to just sit down. We're gonna probably
make it a point because there's so many people in the class to just hand them out while I
start lecturing. This way we don't have this big bottleneck of p ...

Hey everyone. I have one handout for you today. You don't
have it in your hands because we're gonna pass it around. I just really have the one. I'm
gonna have T.A.s pass it around during the lecture. I sent out an email on Saturday. Did
anyone not get that email? Probably a handful. Oh, wow, nobody ...

Both of these are all the exam problems, so they’re certainly good problems to
understand the answers to. And if you’re not gonna watch the section or attend, just make
sure you at least read the handouts. You may very well be able to do the problems
yourself, and if so then that’s fine, but if not, ...

I’ll explain how that works, in a second. Because this is managed by software, malloc,
free and realloc, the person implementing that can use whatever heuristics they want to
make it run as quickly and efficiently and, obviously, as correctly as possible. And so
we’re gonna talk about some of those ...

You also get your fourth assignment today. I'm gonna make it due next Thursday
evening. I will tell you now that this is the one that surprises everybody a little bit. It's
certainly doable, but there are aspects of using the vector and hash set that always take a
few people by surprise, particularl ...

It’s going to be videotaped. I’m gonna call SCPD after the lecture today, and try and
make sure that they post it by 5:00 p.m. today, so it’s around for the weekend, online, so
you can watch it. But I’ve already, I think, pretty well advertised it, Assignment 4; I think
to be kind of the biggest sur ...
