Yes, I think we have a misunderstanding. I use Maxima actively, but I do not want to include its calculations in my document. Really, what I'd like specifically is: 1. LaTeX document 2. Ability to define macros locally and more easil

Alright, so I work as a mathematician and I'll strongly agree that there's not good substitute for TeX at the moment for producing mathematical documents. That said, I do periodically look for something better because it's f

Which paper are you speaking about? Certainly, I'm always interested in a more complete history. I'm currently on LeCun's page and can't figure out which paper you're speaking to: http://yann.lecun.com&

I would even say that this is somewhat revisionist history. From my perspective, this all started from an attempt by Kolmogorov to solve Hilbert's 13th problem: https://en.wikipedia.org/wiki/Hilbert%27s_thirteenth

Actually, that's an interesting thought. I just did a quick check of the FFI and it looks promising. Thanks for the the idea!

Funny enough, std::visit was one of the features of c++17 that I was looking forward most to. Something that I don't entirely understand, though, and the author brings up is the lack of a function like make_visitor. Does anyone under

I would also say that clothing is a form of communication. Certainly, it's one that you may not value, but I believe it's something that we should be aware of if we're to be effective communicators. First, there's the

I'll also contend this is a disturbing, terrible idea. I design optimization algorithms and software professionally and the majority of that software is released open source. Now, does my software likely run terribly on some problems

Are there any LuaTeX users here? At the moment, I use XeTeX to generate software manuals. Technically, it all works and I'm able to import code samples directly from source into the manual using the listings package. I'm also a

That's true and many of those criteria are interrelated such as race and poverty. That said, there are a couple of points that distinguish race over these other issues. First, the numbers for underrepresented students are pretty terri

The grand parent comment asked, "In short, are the Krylov methods (or perhaps other approaches) a bit too precise in their attraction to critical points?" to which you replied, "Exactly. Saddle points are like a magnet for th

by kxyvr 9y ago
Absolutely not. Krylov methods are one method for solving a linear system and can absolutely be used with stochastic optimization methods. Generally speaking, most optimization algorithms require the solution of some linear system and we

I think one of the problems is that calculus teaches us the ideas that there's an construction called a derivative, but in reality there's lots of different kinds of derivatives with different semantics and types. For the vast am

I very much agree! Barring some kind of special intuition to the problem, I think ML are a fantastic tool for building models from empirical data. Even with intuition, sometimes they work as well. My core argument is that anthropomorphizi

by kxyvr 9y ago
That may very well be and I think it's a fantastic area to do research on. Namely, can we accurately model the body with an algorithmic process and what does this process look like? However, unless ML directly mirrors: the algorithms

Thanks for chatting!

by kxyvr 9y ago
For the analogy to hold, it's more of a question of whether or not ML algorithms operate in the same way as the brain. Right now, ML models use algorithms from continuous optimization that require certain structure. Namely, we requir

Unless I'm missing something, and I likely am, the linked paper is still based on the the fundamental assumptions behind curve fitting that I listed above. Namely, their optimization algorithms, metrics, and models are still based on
259.
by kxyvr 9y ago
Alright, so from my perspective, curve fitting consists of three things 1. Definition of a model. ML models like multilayer perceptrons used a superposition of sigmoids, but newer models have superpositions of other functions and more nes

by kxyvr 9y ago
I believe the process for deriving fundamental physical models differs from the techniques used in ML. For example, say we want to use the principle of least action to derive an expression for energy similar to what Landau and Lifshitz der
261.
by kxyvr 9y ago
I don't think so. There's an incredibly important art and science to model selection that is not encapsulated in curve fitting. For example, say we observe a boy throwing a ball and we want to predict where the ball will land.

Thanks for putting that up! Have any interest in piping that page into an RSS document?

by kxyvr 9y ago
Interesting. I've not heard that term before. Can you suggest a personal data management tool that works well with one of the suggested backup solutions in this thread?
264.
by kxyvr 9y ago
Perhaps someone could offer a related suggestion. At the moment, I use rsync to backup files to external hard drives. One of the difficulties that I run into is that some folders I want to mirror exactly between my computer and the backup

In current practice, there's plenty of roughnecking work that involves action beyond slinging pipe. There's a huge amount of monitoring, surveying, and other engineering work that has nothing to do with physical strength.

Off and on, I do contract work for oil companies and I can say with some certainty that it's a pretty hostile environment toward women. Let me give some examples to see if I can build a picture. On the technology end of things, I used

Candidly, there are plenty of people who delude themselves that they are well suited to being a doctor or lawyer. That said, they're prestige positions, so there are cultural reasons for doing so. On the STEM front, a quick search imm

This is factually incorrect. Many years ago, I was involved in underrepresented minority outreach programs at a variety of institutions. Computer science was one of many fields, which we focused. Though, to be clear, the programs that I

Thanks for the info! That does help quite a bit. I really have gotten a lot of mileage out of your packages, so I appreciate the hard work.
