It's not totally clear to me whether there is a real story in ML/AI or neuroscience.

The authors used logistic regression to try to determine whether a subject will remember a word or not, which the classifier did better than chance, but still did pretty badly, with an AUC of 0.61. Then, when the classifier said the probability of remembering the stimulus is less than 0.5, they sent some current through some electrodes. The set of electrodes to stimulate and the current were selected in consultation with a neurologist and fixed at the start of the session. They found that stimulation in the lateral temporal cortex was associated with a significant (but just barely) increase in recall compared to no stimulation or stimulation outside of lateral temporal cortex. (But it's unclear whether this decision to look at effects in LTC vs. outside of LTC was made a priori. If it was not, and many comparisons conducted before arriving on this story, then the effect may not be statistically significant after adjusting for the comparisons.)

Beyond the question of whether the outcome was selected post hoc, the main problem with the study is that, unless I have missed it, there is no control to demonstrate that selecting the trials on which to stimulate using the classifier is better than stimulating on every trial. This control seems necessary to demonstrate that the linear classifier (which is apparently now "artificial intelligence") is in any way useful. Otherwise, this paper has little scientific value, short of possibly providing another data point regarding the effect of stimulation upon memory.

Russias ruling elite need external threats to keep their reign secure, otherwise russians would start looking inwards rather than outwards.
The streams/sinks work in the IO monad and that induces an ordering of the effects, yes. Within the callback, you can still do things like filtering or taking only a part of the stream.

Returning the stream itself from the "withFile" and trying to run it later still is still a bug.

I like this approach better that conventional Haskell lazy I/O, which I personally find quite confusing.
As a person who LOVES pandas, numpy, scikit, and all things SciPy, I really wish these kinds of posts would take a few seconds to include a link, or maybe just a quick paragraph, to answer one question:

What the %$#@ is Ray?

I make a habit of doing this myself whenever I do a post like this. Sure, I was able to look up Ray from the Riselab and figure this out myself, but I wish I didn't have to.

From the Ray homepage:

Ray is a high-performance distributed execution framework targeted at large-scale machine learning and reinforcement learning applications. It achieves scalability and fault tolerance by abstracting the control state of the system in a global control store and keeping all other components stateless. It uses a shared-memory distributed object store to efficiently handle large data through shared memory, and it uses a bottom-up hierarchical scheduling architecture to achieve low-latency and high-throughput scheduling. It uses a lightweight API based on dynamic task graphs and actors to express a wide range of applications in a flexible manner.

Starting tomorrow, you will eat peanut butter toasts everyday... (peanut butter with no salts, sugars or oils added and the bread should have the least number of ingredients possible that you can easily find) ... just kidding.
That's a flawed argument that has no coherent cause-and-effect chain.

"Legally" is the only thing that matters and can be regulated in any tangible way. You cannot and should not enforce artificial constraints on legal and humane social trends, because unequal outcomes are the result of free will and a free market -- yet the prevailing narrative now essentially equates lack of equal outcome in professional fields to human rights violations, and that's a terrible thing to do.

It is neither the government's nor anyone else's obligation to make certain people (of both genders) who are not hardworking, intelligent or ruthless enough have the same outcome as those who do achieve great things due to those and other factors specific to them (this includes such simple things as requesting/demanding higher pay, which in itself requires certain characteristics present in a larger quantity in men due to being inherently aggressive creatures biologically).

This kind of argument reminds me of a comparison I heard a while back between the left and right: the left believe humanity is inherently nurturing, while the right believe humanity is inherently competitive.

Both are true, but the left-aligned media is currently pushing the former at the expense of the latter, resulting in the right-aligned media going hyperpartisan as well.

Meanwhile, they're forgetting that the truth of competition (ruthless, primal competition that's masked by modern civility) has always and will always remain an inseparable part of humanity, resulting in all sorts of inequalities and differences in outcome based on human input, in the same way my Macbook could have produced the Evernote app had I been the one with the idea and skills and foresight to create it at the right time rather than someone else.
This is a solved problem that has mostly to do with propeller shape. By creating 3D simulations of airflow you can come up with very quiet designs.

The reason it’s not done is because no one gives a damn. Planes and helicopters fly too high up and if you’re in one of these vehicles the sounds of the engine will be louder than the propellers anyway because they aren’t electric.

The military however already has this tech.

Clearly this is an orientation video that is going to play in the waiting area for people who are using a self driving car for the first time. Its calm, everyone around it is calm, and nothing unexpected happens during the entire video.

I of course want to see the video where the human drivers do things that human drivers do. They illegally pull out of left turn lanes to go straight, they fail to stop when they turn right in the intersection you are about to enter, they make an illegal u-turn when they realize they turned the wrong way. What does the car do when someone tailgates it? What does it do when pedestrians step off the curb but then don't cross? Watching how the car navigates those situations would make me feel a lot better than watching it drive around where everyone was following the rules.
Oh, absolutely. It's just that I'd rather read more interesting insight on what we do know rather than a tangential attack on how Autism and gut yeast can't be related. I guess it's similar to a lot of more controversial topics where the dialogue is often narrated by extreme viewpoints rather than the more reasonable middle ground
This study is interesting, but it's not really AI and it's not really novel.

The researchers fit a regression to predict word recall from high-frequency EEG activity when memorizing the word. We've known for several years that high-frequency activity predicts memory success, so this part isn't new.

In addition, several papers have tried to improve memory through high-frequency stimulation from brain implants, with various results. This paper proposes "closed-loop" stimulation, delivering stimulation only when the classifier predicts failure. They find that closed-loop is effective.

What the authors really want to claim is that closed-loop is more effective than open-loop, because otherwise their fancy "AI" classifier is useless. Surprisingly, this study does not compare closed-loop vs. open-loop.

There’s definitely some truth to this. In my experience sales and negotiation skills play a huge part in compensation. I don’t recall those ever being taught in school. Also basic financial management is sorely lacking.
Ditching in NYC is pretty easy as there is a huge body of water next to it (also, why airports are built near water if possible).
It's a myth to suggest the NHS is heavy on bureacracy. The NHS has less management than most UK business, and often those managers are dual role clinicians / managers.

https://www.kingsfund.org.uk/projects/health-and-social-care...

> The NHS Information Centre shows that there were about 43,000 NHS managers in 2009 (about 3.7 per cent of the total workforce), although this figure does not include many clinical managers.
How does this compare to other sectors?

> According to the Office for National Statistics, the proportion of managers in the UK workforce as a whole in June 2010 was 15.4 per cent. These statistics also show that there were 77,000 hospital and health service managers across the United Kingdom, or 4.8 per cent of the NHS workforce. In other words, the NHS has a managerial workforce that is one-third the size of that across the economy as a whole.

Some loose thoughts:

A lot of this boils down to figuring out a delegation model that works for Elm.

Does the BDFL of the language really also need to be the only person maintaining core libraries? The only person maintaining project communications?

In this particular case it feels like the Elm team is afraid of "losing control" over the language.

That's often in direct contradiction with the project becoming more popular, so for a while maintainers need to choose between advocating the thing they're building and advancing it in the way Elm is currently being advanced.

Once things like [1] start appearing in the codebase you're basically asking people to fork your project and what happens after that is unknowable ...

What makes you say that there's no agreement as to what it means? It feels like I see this sort of view expressed quite frequently.

One fundamental problem is that the GDPR, if interpreted literally and fully enforced to the letter, is absurdly onerous for any small organisation and allows for fines that pose an existential threat without any requirement for proportionality.

Defenders of the GDPR, including some of the official regulators, often argue that concerns are exaggerated and regulators are likely to take a more pragmatic approach, trying to educate those breaching the rules rather than coming in with crippling fines. Maybe that will turn out to be true, but in past instances of overly powerful or broad EU rules, there certainly have been cases of heavy-handedness by regulators and courts, so it is illogical to rely on another result this time.

In any case, pragmatic enforcement would not make the law itself any better. Those responsible for working with personal data still have to err on the side of going too far in their efforts to comply, and thus finding themselves at a disadvantage compared to their competition who do not, or not going far enough, and then risking a regulator dropping the sword of Damocles at any time, with no objective standard for "far enough".
I believe that means competitive rowing.

Rust is a language, and it can bind to C libraries. Java can import DLLs and shared libraries. Haskell can do this too. All popular languages that can run on a server can spawn a process and communicate via file descriptors.

Useful languages can interop with other languages.
Not according to TFA. Do you have a source for your counterassertion? I doubt Tyler Rogoway would get such a point of fact incorrect - even when I've disagreed with his analysis I've never found him to be dishonest.
I'm a little confused as to why you're being down-voted, save your audacity in being cautious about nutritional "experts" having a poor track-record in their dissemination of advice. Mere decades ago, the statement that a high-protein/high-fat diet is optimal would fly in the face of expert-opinion. It is not so many years ago that using trans-fat laden vegetable oil was considered "healthier" than using rendered fat.

You have stated in a common-sense way that ingesting huge quantities of sugar and trans-fats make you feel terrible, and ingesting leafy greens make you feel physically well; not that one should simply eat what their cravings tell them to. As sensitivities to certain foods can manifest themselves in different ways on an individual level, recommending that people pay close attention to the impact that certain foods have on their energy-levels, mood, and performance is sound advice.
I've always considered the idea that the Cold War was "over" to be nothing but propaganda designed to prevent people from wondering why their nation is spending $Trillion on their military.

Of course the Cold War is still happening: America has been exporting war wholesale for decades. Just because Russia hasn't been doing it at the same scale as well, doesn't mean squat.

The US and Russia have had plenty of opportunities to leave each other in peace over the last 30 years. The trouble is, they're not the only parties to this farce. Incredibly powerful, massively entrenched super-power-like military industrial multinational corporations are involved as well, and there is no way in HELL they are going to let their number one revenue source dry up just because we all want peace.

Its quite simple: stop assuming that its sovereign nation states doing all the fire-lighting. We are way, way beyond that point now. If you want to get a grip on war economy you have to stop allowing your politicians to push you - the people - into more and more heinous debt, for more and more heinous reasons (imperialist warfare against innocents), without repercussion.

This is going to be a tough sell. Pretty much everyone using computers to establish themselves in the technology markets today is going to have to deal with a multinational, war-mongering, mega-corporate military-industrial giant. We're well and truly being dominated by those who are quite happy having us all in the abyss, trembling in fear at what would happen if we stopped buying from General Electric, Samsung and co.
The GP comment has the hallmarks of Chinese gov't propaganda, which reaches even here. You'll see it every time criticism of China appears: 'The U.S. does it too.' Sometimes the application of it is just laughable:

> Americans movies will certainly never paint America as the bad guy

Wow.

> There is a lot of bad blood coming out of American media about China

The paranoid, we're-picked-on perspective.

Much of the comment is directly from the rhetoric of the Chinese Communist Party and government:

> Anyways, movies are political statements. When you make it too real, then it hits too close to home. And there are certain dangers with that kind of propaganda. And it will certainly upset the people on the receiving end of it.

Everything is political. Avoid politics that challenge the Chinese Communist Party for reasons of public order, which just upsets people - the public doesn't want to think about politics and become upset. Promoting Chinese Communist Party-approved politics is ok, because that increases public order.

> Stick to making movies about aliens and their probing devices, zombies, and superheros in tights. Or killing the evil German Nazis. Nobody will question these kinds of movies.

Uh, I'll try to keep that in mind. We wouldn't want to make a movie that anyone questioned!
So basically what people like Jordan Peterson or James Damore were claiming, lucky for this woman she is not working for Google. Also, why success in high school should indicate anything about success in work? High school is easy for anybody who is willing to put the time and effort unlike university or just doing your own project in your garage which is typically a male thing. High school is ticking boxes, it doesn't indicate ability to innovate, to create new businesses and to push knowledge forward, this was always the male domain and still is.

I also don't like the assertion that being a lawyer or a doctor or a teacher means helping society. The technology created by men helped society much more than a lot of those professions which are just a perpetuation of what women used to do in the family to the workforce. Men create the real value in the economy, women take care of kids and adults as in teachers, social workers doctors or they move the value male created around as in lawyers, bankers and sales persons.
For one example of politicians chosing to ignore NICE look at the Cancer Drugs Fund.

The CDF makes available cutting edge new technology to people dying from cancer. These meds are very expensive. They often fail the NICE appraisals. The CDF pays for the meds.

We know that these meds often don't work at all, and sometimes cause harm, and are fantastically expensive.

As someone who has been shopping on Amazon since the late 1990s I have recently stopped buying anything branded on there anyway, or at least anything branded where I care about receiving real OEM products. Still a fan overall but one too many knock-off products for me.

After a few years of using Amazon pretty much exclusively for everything then going back to other sites for branded items, I have been pleasantly surprised how much better "all the other" online stores have gotten at fast free shipping and reliable service.
I'm sad that the AI acronym has become overused, and has lost its credibility. Back in 2004 even the expression "Expert System" was warily used, and only when appropriate. The way this is going we're going to have AI toasters by the end of the year.
Hopefully they will sell knockoffs from China.
This is a lovely bit of kit, and if i had stacks of spare money, i would absolutely buy one.

But. What is this for? if you want uncompromising image quality in all use cases, the A7 is competitive with Canon and Nikon, but not clearly superior. If you want the compactness that mirrorless can bring, Micro Four Thirds' smaller sensor enables very significantly smaller lenses, requiring only the sacrifice of low-light sensitivity. It think it falls between those two stools.

Mind you, i say that as a Micro Four Thirds owner. Perhaps i'm biased. Still, if i was going to add an expensive big camera to my arsenal, i'd probably jump all the way to medium format!

Apart from (parts of?) the US - most civilised countries have strong rules against entrapment. It's eg unlikely the first twin tower bomber could've been found guilty, as FBI initiated the plan and provided the explosives.

That doesn't mean police can't do "minor" entrapment in order to roll up a big case; it just means they can expect to sentence people for those acts.

As for a litmus test, I believe maiming or killing bystanders would qualify against most police officers (the trick, then is to make sure the "victim" isn't a carefully placed undercover asset...).

Now, assume a ring of human traffickers have the rape and killing of a victim as part of the initiation process: are there circumstances where we would condone branches of our government to participate in order to bring down such an organisation? I lean strongly towards no; but as has been seen from Japan under us administration to kfor in Kosovo - using war criminals and military/intelligence personell as part of heinous organised crime is a feature of our current world order. How do we fight it?
If I recall correctly, Elm grew out of Mr Czaplicki's PhD thesis or project. It seems that he still considers it _his_ project, which is fine for him and his employer but it does it make it hard for those not close to him to see where the language is going and get support.

In a perfect world (according to me), Elm would have 5-10 people in its core team, with at least a few of those tasked with triaging issues and PRs. That wouldn't mean "giving up" control of the language and its future.
I would definitely suggest not using epilepsy patients as lab rats. First off, the article says "Machine learning is inherently notoriously inscrutable" which is extremely wrong and ignorant. Then they proceed to demonstrate how they essentially failed to force people to memorize useless words on a screen, by zapping their brains while not really know what they're doing or how anything works. This is NOT my idea of ethical, late-stage pre-market human research. This is something to do on rats, not people. This is the same as shock therapy of rebellious women in the 60's. It's horrible, has irreversible side effects and you need to stop doing it. These are people, not toys for PhDs.
