I'm not able to make sense of why it would not just be region-based memory-management. ( http://www.sciencedirect.com/science/article/pii/S0890540196... ). The usual way this fails is that everything end

FAIRie here. GA is essentially guess-and-check. SGD doesn't require guess or even check; if your error function is differentiable, and you didn't screw up the chain rule, you know what direction to head in to make it go down. For

So, convolution is by itself an attempt to exploit translation-invariance in the visual world, and typical deep convnets end up picking up a certain amount of scaling tolerance (though I would not call it invariance) by having features th

The win here wasn't about scale, though. A tiny fraction of wikipedia users are logged in. The win here was about individual page load time. And page load time is just as important, if not more so, for something new trying to vigorousl

Thanks for the kind words. For context, I'm an HHVM alum who has been at Facebook for almost six years now (wow time flies). From my point of view, most of what has changed is resources and the immediacy of our survival-level concerns.

As far as I know, you could try tracelets with any dynamic language. And yes, you could try to share tracelets whose bodies are identical, but, unless their successor tracelets are also identical, you'd need to "dynamicise" t

Hi, I'm one of the paper's co-authors. As usual, the abstract really isn't enough to draw big conclusions from. The concept of a latent type applies to arbitrary expressions, not just variables. All the values flowing through

By sheer coincidence, Michael Jordan did an AMA yesterday, and made this case better than I could. http://www.reddit.com/r/MachineLearning/comments/2fxi6v/ama_...

Hey, nice to make your acquaintance, and thanks for offering your contact info. Mine can be backed out my HN profile as well. I actually work in Menlo Park; the AI group is split across New York and Menlo Park, with a very small European co

Hi, I am a research engineer in Yann LeCun's group at Facebook. I hate to seem to be picking a fight, but you're a prominent poster here, and this comment seems likely to garner a fair amount of attention. Unfortunately almost eve

Cliff Click, a smart man in whom I see many admirable qualities, than whom there are few more complete experts on the JVM, gave a tech talk at Facebook about how Java is faster than C++ just a few months ago. Tons of perfectly smart enginee

Yeah, almost everyone in the real world is using it via FastCGI. People have a huge investment in the configuration and operation of their existing http server (nginx or apache).

No. This blog post is about HHVM. The PHP to C++ translator was removed from the HHVM source tree back in February. (I'm an HHVM team alum.)

(HHVM alum here). Sorry you had a tough time. What's changed is that time has passed, and the HHVM team has put a lot of effort into closing the compatibility gap. If you are aware of a bug with namespaces or traits, let us know at ht

Video of the talk is not up yet, and it's a little cryptic with just the slides. But one of the points I was trying to make is that PHP actually makes you more likely to be successful than a lot of its competition. The lolsy stuff on

Hey, HHVM alum here. The outright language gaps to 5.4 are few and fairly obscure these days, in my opinion. Most practical problems are due to missing or slightly misbehaving extension functions, rather than the core language. You can writ

Hey, I'm Keith and am one of the subjects of the story. HHVM is a much, much smaller undertaking than rebuilding Facebook from scratch. Wired did another article from the same source interviews about just how big Facebook is these days
