Finance differs fundamentally from most other machine learning domains because new data diverges qualitatively from trained data so much quicker. Roads aren't reconfiguring themselves daily to to avoid being detected by a self-driving car; tumors aren't really appearing any different on mammograms than they were yesterday.

So whereas in most domains, a large, growing and representative corpus of data should allow a wide range of ML approaches to steadily decrease their error, in finance the error will generally increase over time for any particular classifier approach, unless it is a sufficiently dynamic meta-approach that produces new classifiers in an ongoing way as new data becomes available. (And even then, the new data is only marginally better than old data at predicting the nature of the market tomorrow -- it's still way more unpredictable than traffic.)

How do you produce a sufficiently dynamic meta-approach, to produce new classifiers on an ongoing basis that are actually good? You need to discount the value of large amounts of data, because that data is fundamentally less predictive than data in other domains; and you need to strenuously avoid fitting to irrelevant signals in the data. This is harder than just not overfitting in a typical way; yes, you need to not allow too many independent values in your model relative to the amount of data. But you also need to attentively inspect and guide the consideration of the signals that your model tries to use, even if there aren't too many of them.

Here's where neural networks, and genetic algorithms, are especially difficult to use in finance: they are more opaque to human inspection and selectivity, and so they lower the ability to discover elements of a model which are of suspect value. A less sophisticated approach like various regressions and decision trees, on the other hand, are easier to inspect and thus allow for more careful human-computer cooperative iterative design.

In a domain where the data aren't trying to squirm out of your hands, you can let testing error show you how to iterate in your meta-approach to producing classifiers; your classifiers will get better. But in finance, that iterative process may not improve your classifier production method fast enough to keep pace with the changing data, and so you need a process that requires less practical failure, and instead uses more human understanding and inspection, to guide iteration.
how does it fare on time complexity compared to normal tests like say AKS?
I think it depends on how much you treasure battery life. Electron based apps suffer from poor battery life due to the Chromium unpinning. JS is resource intensive compared to C++. You can probably get an extra 20-35% battery life out of Sublime vs Atom. If you don't have the ability to plugin while out, it might be worth the piece of mind.

I worked for Audible for five years, and this exact conversation was had often in my division (ACX.com - Audible's "Audiobook Creation Exchange".)

Audible brought ACX together in order to bolster its catalog. The company-wide initiative was called PTTM ('pedal to the metal') and ACX was Audible's secret weapon to gain an enormous competitive foothold over the rest of the audiobook industry. Because we paid amateurs dirt-cheap rates to record horrible, self-published crap (to which Amazon, Audible's parent company had the exclusive rights), Audible was able to bolster its numbers substantially in a short period of time.

The dirty not-so-secret behind this strategy was: nobody bought these particular audiobooks. These audio titles were not really made to be "purchased," but rather to bulk up Audible's bottom line. We knew that the ACX titles were not popular, because the amateur narrators' acting talents and audio production skills were remarkably subpar.

Neural nets may be able to narrow the gap between the pros and the lowest-common-denominator to the point where they can become the next "ACX," but frankly, it won't matter to audiobook listeners, because audiobook listeners don't buy "ACX" audiobooks. Books, even in audio form, are a major intellectual and temporal commitment (not to mention -- they tend to be pricey.) Customers will always want to buy the human-narrated version of a book - the professional production of a book. If that stops being offered, Audible will anger a lot of customers and I think Bezos has better shit to worry about than his puny audiobooks subsidiary.

Despite that, user-generated content is a secret weapon that a lot of websites wield effectively - including HN - but this is beginning to shed its effectiveness. Indeed, the next generation of cost-slashing-while-polluting-the-quality-of-your-catalog will belong to the neural nets. They may be able to get better sales than ACX titles do today with AI-generated audio content, but the actors are going nowhere.

Horrific. It's implicitly checking for every divisor (which is O(n)) but there's also the complexity from using a regex engine (which can be O(n*m)). So the overall complexity is probably of the order O(n^2).
That succinct explanation was excellent. Something like that should be a sidebar to the original article.

In the hedge fund world investing in these short duration, volitile debt is called "picking up pennies in front of a steamroller", meaning, if the market doesn't crash this month, you'll earn a few excess basis points of return, if the market does collapse you'll experience 100% principal loss.

Why do the entrepreneurs chose to do this? Well, raise $100m from the Chinese, retain 5% of the equity , and hope you get liquidity before the bottom falls out. Essentially an option on an option, but with no money down.

Better question is: why do the engineers do it? And why are they willing to blog about it??

My understanding is that only one part of ML - regression has similarities with curve fitting while classification/clustering does not. What is the equivalent in curve fitting where the goal is to find which points belong to one specific group (of points) rather than the other (clustering)?

Curve fitting makes sense for cardinal values (countable quantities), but usually does not for ordinal (numerical, but not countable, usually indicating order - e.g. rank, review scores) or nominal values (male vs female, zip codes) because you cannot even plot these as x-values on a graph in a meaningful way.

You'd be surprised - I work for an ISP that sells five nines SLA on most of its circuits, and meets it. We spend money to do it. Having 1+1 redundant core and agg router sets at every POP, geographic diversity of inter-metro fiber, full A and B side power/rectifier systems, etc.

With the right BGP and ospf design you can absolutely meet five nines availability for an end user customer perspective. We have some places that are approaching six nines.

This article reads like they had 1+0 everything and ran into a nasty iOS bug. Running out of ram is amateur hour as well.

When we need to do customer service impacting maintenance that will totally take their segment off the net, the hit can be from 15 seconds to a couple of minutes. And that is in a case where a colo customer is single homed to a single aggregation switch like one of our 48-port 10GbE aristas.

Pretty light on the actual warfare (besides poaching the other side's scientists and librarians, and the export stop for papyrus).

IIRC, they did also confiscate scrolls from merchants who set foot in their ports. I was looking forward to more stuff like that and even more sinister stuff.

As described here it was less a "war", and more "competition".
Success with interns
An emphatic male absolutely does know more about what "women are going through" than, say, a narcissistic female just parroting lines she saw work for others, ripping other females to shreds as she strives for power. If you honestly have not ever seen that, keep your eyes peeled.

If anything, I'd say privilege based on treating people as abstract monoliths and having double standards, and being unfair and abusive towards others did cause and causes "the problem", one a symptom of which you call "the" problem.

You know nothing about what others think about, what they know or don't know. I grew up with mostly female friends, always loved to work in mostly female teams and am at the moment, too, and one of my proudest childhood moments was a 13 year old female friend telling 9 year old me that I'm "the only one I can really talk to around here". I believe in being fair irrespective of person, and being supportive to ANYONE who needs support, and that besides making them laugh surely is one of my qualities my female friends would not ever want to miss in me. If I was as I am to them because they're a woman, that would be regression, plain and simple. For me people are persons first, things like gender and age second, and people who think there is "being a woman" versus "being a human who happens to be female" I want to have nothing to do with. I feel exactly the same way about men who do the reverse.

Anyways, crawling on one's knees because of identity politics is BS. Don't interrupt others nilly-willy, listen, don't presume, don't be rash. Don't trample on "small ones", be a compassionate person and show it. This has nothing to do with where you are or who you're dealing with, and nothing to do with gender. It's called being a good person, and this talk about empathy is really like blind people talking about colors. Why not simply recognize the psychological make-up of people by dealing with them, not by gender or nationality or other statistical probabilities.

To sum up, not only is something way better, way more thorough and honest possible, it's being done every day, all the time. It's just those people quietly enjoy being decent to each other.

If you have a single source file that's big enough for the compiler to bog down on it, then either that compiler is beyond ridiculously slow, or you need to refactor.
For me, it is. Some of the main points that makes it worth money to me are the plugin ecosystem is huge, the editor is fast, its layout management (panes in columns/rows) is incredible, and it was the first editor I had that gave me multi-cursors. I like where VS Code is going and I try to use it when I can, but most of the keybindings and shortcuts I have memorized are for Sublime and IntelliJ based IDEs.

I agree with the idea that there are inefficiencies, unfairnesses, externalities in the "legit" way of operating short term rentals. But there are many hotels without 24/7 customer service, where the front desk is closed after 10pm and you get to call a number with urgent needs (like plumbing failures or whatever), etc. And they are cheaper than typical hotels, as are typical bed and breakfasts as compared to the boutique b&b's. So it's completely fair to be critical of all of these inefficiencies, but I think it's wrong to suggest AirBnB has some particular innovation other than their app connection buyer and seller, and themselves evading and enabling others to evade, the level playing field. Such as it is.

For anybody interested in the topic of abuse, I strongly recommend, "Why Does He Do That? Inside the Minds of Angry and Controlling Men": http://www.amazon.com/Why-Does-He-That-Controlling/dp/042519...

It is the single most astute book I have read. The author, a domestic violence counselor for men, mostly had clients who were court-ordered to attend his sessions. He spent a decade listening to vast amounts of self-justifying bullshit and then wrote a thoughtful, precise, and clear breakdown of why and how abusers work and how the abused can get out of it.

At this point I've given away 15 or so copies. Some to people who needed it urgently, and many to people who just wanted to learn more. Ignorance gives abusers cover, and I honestly think this book should be required reading for every high schooler so that they can spot and call out patterns of abuse.
If that's really a worry, invite 3 women. That will make it clear that it's not a date, and it'll be much more likely that they'll feel safe talking about gender issues if they know they'll have backup and confirmation.

I'm not suggesting there are no oil soluble materials in mushrooms. But just because there are such materials does not mean there is any such thing as "truffle oil" or "mushroom oil" in the same way there are nut, avocado, and olive oils which are produce by extraction. To actually get truffle oil would be insanely expensive and insofar as I'm aware, there's no evidence either the flavor or smell we're interested in with truffles is even in its own (minimal) fats.

To me, treating people like means paying close attention to what they have to say about their lives. Like it or not, some kinds of visible difference have a major effect on people's lives because of how others treat them.

We are slowing emerging from millennia of patriarchy. Insisting on pretending otherwise doesn't sound like treating people as people to me. It sounds like insisting that they conform to your expectations, which I think is pretty much the opposite of treating them as people.
I don't know what to tell you man. We can just look at the article. Or any of the posts in this thread that claim to be from a woman.

Every post from the article seems to support my claim and not yours. Thats only N= 4 or 5, but thats still something.

"and the implication that you have enough information to conclude that the parent simply _could not_ have already talked to women engineers "

Yes, this is indeed my implication. That he could not have possibly already talked to very many women.

I would say the same thing if someone were to claim "Racism in America is over!"

Such a person who makes this claim has clearly not talked to very many black people, or hasn't listened to them.

He mostly talks about proof assistants for general mathematical theorems, something I don't use, but in TLA+, proofs are of logical formulas, the steps are logical formulas (unlike in dependently typed provers), and a computation is just a (temporal) logical formula, so TLA+ already lets you incorporate computations into proofs, but the process isn't automatic. Then again, TLA+ isn't really designed nor used as a general theorem prover (though it certainly can prove general mathematical theorems) but as a tool to specify and verify algorithms.

Not to knock this project, which seems well executed, but I'm always a bit ambivalent about digital frames. Sure it's kind of neat to to be able to have changing images, or at least be able to easily push new images to the frame, but they're always so impractical.

You either have a wire you have to hide, or you have to remember to charge the frame regularly. All that costs energy. Then of course it's always backlit, which seems odd. Do I really want a glowing rectangle on my walls? Not really. It kind of kills the vibe. Perhaps eink would be better, but beating dyed paper is hard.

Not caring about their gender is awesome. You know what's not awesome? Refusing to accept that other people who do care might have had a big impact on their lives.

> Female peers never had any issue with me.

Well, they have never admitted any issue to you. It could be that they have no issues. Or it could be that they've put you in the category of "person not worth talking honestly with." Given that you have a strong aversion to what you see as "special treatment" and they might see as "fair treatment", I could see why someone might be inclined to flip the bozo bit. [1]

This is an interesting take on licences that turn 'abandon-ware' in to public domain or close to public domain code when the maintainers are unresponsive.

I like how it mandates that there are 3 years for innovation to occur within. However I feel like the license before that needs provisions for things like the ability to make local changes as needed, and also to publish /security patches/ freely.

Edit (Beneath):

The impression I got was that he has ONE version, and a built in escape clause for anyone using it. I took the view of this licensing scheme ensuring he'd have to 'compete' against a 3 year old version of the product with compelling features; not that there'd be an intended 'free' version of the product.
