I highly recommend the book 1491, which goes pretty deeply into what we can infer about the pre-Columbian Americas.

Thanks for the questions. I am very unlikely to take on visualization. I don't acutely need it for what I do, and I am some-but-not-nearly-enough interested in visualization for its own sake. I started to read about the grammar of grap

Thanks for the kind words. Breeze does a large chunk of (dense) compute via netlib-java, which calls out to "real" lapack if you set it up. Are things really faster than that? Or are you referring to the non BLAS/non Lapack t

Main author here. Breeze has breeze-viz, which is very basic but at the time there wasn't anything else. I highly endorse using something else. I personally like http://sameersingh.org/scalaplot/ They're unde

So, this is (largely) my project. Not sure why this is on the front page of HN, but I'm happy to answer any questions. I'm not really giving these libraries the love they need these days. I mostly started them in grad school befor

Sure, but the FP side of Scala is definitely firmly in the advanced static type system camp.

Not a neuroscientist, but I do do NLP, and I only lightly skimmed the paper. This doesn't really speak to UG. First, you can believe in the structures they purport to show without accepting the existence of UG, by appealing to the exis

Prosopagnosia[1] is a real condition that affects ≈2.5% of people. You might check out "The Man Who Mistook His Wife for a Hat" if you're interested. [1] https://en.wikipedia.org/wiki/Prosopagnosia

statically checked, but still runtime-determined, matrix sizes can be done in Scala. Doing specialized implementations would require bytecode magic, though. case class Dim(size: Int) trait Matrix[X <: Dim with Singleton, Y <: D

(I'm one of the authors of Overmind.) First, it's important to know that AI is a very broad term. Roughly, there's "modern" AI (machine learning and statistical modeling) and "classical" AI (mostly logic a

Machine translation is no where near solved. Machine translation is still one of the most funded areas in NLP, and the quality is still incredibly bad for many language pairs. DARPA has been running one machine translation grant program or

This article is basically nonsense. The "Deep" here doesn't mean "deep learning"/neural networks. They just mean non-superficial understanding of text (beyond keywords, named entity recognition, and the like.)

> Yes it does. AFAICT it's working well. There are 5 releases in the 2.10.x line and I haven't had a compatibility issue between any of them. This isn't quite true. I have a library (Breeze) that works with 2.10.3 but not

Make the prior art fee scale up by number of patent applications submitted by that entity, then. First one's free. Then $100, then start growing at some small-ish exponent.

Actually, NNs (specifically auto-encoders) are more like a nonlinear PCA. PCA can be seen as an "information bottleneck" where you try to represent an N dimensional space as a K < N dimensional space such that your ability to r

They're not disposable. They reuse them. You get a rather sizable discount (50%) for giving an empty one back when you get a new one.

So, this is a good post and everyone should be aware of these. But kernels ("non-linear" svms) are not a panacea. If you use kernels, then your model will need to remember some non-trivial number of the data points (the "support vectors" th

Huh, I was wondering why I had a bunch of stars on github in the last few hours. (Sad there's no analytics for Github projects.) I'm the lead author of ScalaNLP, and I'm happy to answer questions. It's mostly a scaffolding library for other

Aren't the ram chips usually soldered to the mobo on ultrabooks? Crucial indicates they can't upgrade ram on the XPS13. And a little googling says soldered RAM... Nothing on the Dell website suggests they can upgrade past 4.

I suspect this might have at least a little to do with the Google+ rebranding. Remember how they removed the + operator from search?

I didn't downvote but, pretty much every academic in the CS/physics/stats/math I've met uses LaTeX. Even a bunch of linguists I know use LaTeX. It's definitely not perfect--I really wish there were something better--but for writing technica

I'm somewhat familiar with this work. (My advisor talked to the authors some. I could be misrepresenting it a little, but not nearly as much as the article.) It's not learning to play the whole game. It's learning to cheese (in gaming parla

Option can occasionally be a pain to handle, I admit. But typically it works really well for me. The standard Haskell-ish approach is to use for-comprehensions: val maybeWebpage = for(foo <- maybeFoo) yield { // do things with foo, yie

Just to help sell it some more: autojump basically watches where you cd and builds a model (of some sort) that guesses where you want to go based on a few characters. For instance, I have a project called "structured-prediction" deep in som
