yummyfajitas··on Semantics derived automatically from language corpora contain human-like biases
You're wildly mischaracterizing what I said. I didn't suggest "people can't handle my truth". I suggested the article we are discussing says there are certain truths that ML systems should not learn.

The article explicitly recommends building systems which can't learn those things, and suggests characterizing them is a first step:

"We recommend addressing this through the explicit characterization of acceptable behavior. One such approach is seen in the nascent field of fairness in machine learning, which specifies and enforces mathematical formulations of nondiscrimination in decision-making (19, 20). Another approach can be found in modular AI architectures, such as cognitive systems, in which implicit learning of statistical regularities can be compartmentalized and augmented with explicit instruction of rules of appropriate conduct (21, 22)."

According to the article, the most closely related work "is concurrent work by Bolukbasi et al. (6), who propose a method to “debias” word embeddings."

(Recall that in the context of the article, "bias" is something that generates true predictions that are objectionable rather than something which is false.)

The example the parent poster described is "doctors are 66% male", which could very well be true.

The parent's point is that they may not be absorbing stereotypes from humans at all. They may be generating accurate beliefs about the world from text representations of the world.

See Fig 1 and 2.
yummyfajitas··on Semantics derived automatically from language corpora contain human-like biases
The paper has them:

- An AI correctly infers (simply by reading text) that a physicist is male and a nurse is female.

- An AI correctly infers the gender of humans with androgyonous names.

- An AI infers insects are unpleasant and flowers are pleasant to humans.

- An AI also infers that African American names are more likely to be associated with unpleasantness than European names.

[edit: to those who dislike this comment, can you tell me what you object to? Which of my concrete examples is not in the paper?]

The usual definition of bias in ML papers is E[theta_estimator - theta]. That is explicitly a systematically wrong prediction.

In any case, the paper suggests that this "bias" or "prejudice" is better described as "truths I don't like". I'm asking if the author knows of any cases where they are actually not truthful. The paper does not suggest any, but maybe there are some?

yummyfajitas··on Semantics derived automatically from language corpora contain human-like biases
Do you have any evidence that this effect results in machines making systematically wrong inferences?

Near as I can tell, your paper shows that these "biases" result in significantly more accurate predictions. For example, Fig 1 shows that a machine trained on human language can accurately predict the % female of many professions. Fig 2 shows the machine can accurately predict the gender of humans.

Normally I'd expect a "bias" to result in wrong predictions - but in this case (due to an unusual redefinition of "bias") the exact opposite seems to occur.

(Drawing on your analogy with stereotypes, it's probably also worth linking to a pointer on stereotype accuracy: http://emilkirkegaard.dk/en/wp-content/uploads/Jussim-et-al-... http://spsp.org/blog/stereotype-accuracy-response )

yummyfajitas··on The Dangerous Academic Is an Extinct Species
Similarly, flat earthism is an orthodox theory since it was orthodox at one point and is not completely dead.
yummyfajitas··on The Dangerous Academic Is an Extinct Species
I agree that in some historical time, some of Murray's views might be considered orthodox. That doesn't make them orthodox today - nowadays he's subversive.
yummyfajitas··on The Dangerous Academic Is an Extinct Species
Charles Murray wasn't discussing human biodiversity at all. His talk was on an entirely different topic. No one argued against him at all. They merely disrupted his talk and then assaulted him and others.

The Nazi in question did not engage in any violent acts at that gathering. That makes him a peaceful protester.

yummyfajitas··on The Dangerous Academic Is an Extinct Species
This article is a little odd. It describes conservatives as being worried that professors are "subversive", but it's exactly the opposite - conservatives worry that colleges are enforcing and indoctrinating people in the orthodoxy.

It's the rare subversive academics, e.g. Charles Murray, who are being assaulted and chased of campus for holding unorthodox opinions.

And it's happening off campus as well - for instance, we recently had a peaceful (but unorthodox) anti-war activist assaulted: https://antifascistnews.net/2017/04/09/richard-spencer-just-...

yummyfajitas··on Uber's head of communications is leaving the company
Perhaps you'd prefer to be regulated by the whims of a corporation & their pursuit of profit extraction rather than the democratic legitimacy of government, but thankfully, most of us would not.

On the contrary, most of us would prefer this. That's why yellow cabs are losing market share everywhere that men with guns don't take away their right to choose.

yummyfajitas··on Uber's head of communications is leaving the company
Of course there's a difference.

In a taxi you can rip off a firangi or fail to pick up a black passenger at your leisure. With Uber, this will cause your ratings to drop below 4.3, or your acceptance rate/cancellation rate to drop below/above whatever threshold they use. Then you get kicked off the platform.

Uber is providing the necessary regulation of the system that governments fail to provide.

yummyfajitas··on Uber's head of communications is leaving the company
That's a lot of nice sounding platitudes, but it doesn't really tell me anything concrete beyond "TeMPOraL dislikes Uber".
yummyfajitas··on Uber's head of communications is leaving the company
How are they a worse taxi mafia? They provide more convenient service with fewer ripoffs and far less racism at lower prices.

As a consumer, what exactly should I be angry about?

yummyfajitas··on Uber's head of communications is leaving the company
The comment two levels above said that Uber reduces my daily dose of racism to levels far lower than "daily". The comment one level up says that the study your clickbait article cites supports this point.
yummyfajitas··on Uber's head of communications is leaving the company
Yes, a small amount of racism that I don't even notice is far more acceptable than a large amount which inconveniences me daily.

Racism isn't like homeopathy, where any quantity at all has the same effect. More is worse, less is better.

In that study, the median black taxi rider is passed by 2 taxis before being picked up, vs 0 for the median white (see fig A.6). The difference for Uber is not remotely as large.

yummyfajitas··on Uber's head of communications is leaving the company
Read the study cured by the Atlantic. Uber is vastly less racist than traditional taxis.
yummyfajitas··on Uber's head of communications is leaving the company
Read the actual study cited by that clickbait article. Racism at Uber is vastly smaller than racism via traditional taxis.
yummyfajitas··on Uber's head of communications is leaving the company
No, they didn't play us. They did exactly what they promised. Thanks to Uber, I don't get racially discriminated against on a daily basis. Before Uber I did.

Some folks may hate them because of Susan Fowler, but that doesn't change the fact that they've drastically improved the world for consumers.

Similarly, I feel that a car shouldn't drive too fast. If it does drive too fast then a human running after it might be unable to catch up!
yummyfajitas··on Why We switched from Python To Go
Apart from the boilerplate enclosing class (4 lines, vs 2 in C), you can write a C-style program without classes in Java. There is literally nothing stopping you and generics are helping you significantly for this.

It could be. In that case, was Rosa Parks also immoral? If not, why not?
yummyfajitas··on Why We switched from Python To Go
Could you illustrate what you mean by "bloated syntax"?

Everything else you mention (besides native executables) Java also has. From what I can see, Java provides far better concurrency support - more paradigms than simply go routines.

yummyfajitas··on Why We switched from Python To Go
There is no requirement to use an ide in Java. I've never written Java in anything other than emacs and never had a problem.

So if a restaurant served people of both races but gave them all a bill, you'd be similarly opposed? Or if blacks broke the law to draw attention to discrimination in employment or occupational licensing? After all, someone (a corporation in the restaurant case) is making money off it so it's just breaking the law.

Or if Catholics in Northern Ireland were protesting to stop discrimination against them in employment, same thing? (Springs to mind since I just visited Derry a few days ago.) Due to the involvement of money it's just breaking the law?

Similarly, Isis Brantley fought for 20 years for the right to braid hair. I suppose you oppose her actions too? http://www.cosmopolitan.com/style-beauty/news/a41742/isis-br...

That's a new argument which I don't agree with, but I suppose the implications aren't quite as bad as those of Markoff's argument. You aren't condemning all civil rights activists, just the ones who fight for an equal right to make money.

Or perhaps you are just making a post-hoc rationalization for a less justifiable position.

yummyfajitas··on Why We switched from Python To Go
If you really want good static typing while being fairly python like, there are other great options. Java or c++ both have decent generics, speed comparable to go, great libraries and years of collective experience using them.

I truly hate the social hacks that are causing go to displace much better languages.

yummyfajitas··on Difficulties accessing medical services as an EU immigrant in Germany
Medicine is always wonderful if you are a petro-monarchy prince. I'm just a regular guy.

Anecdotally, I've been told that a lot of middle Eastern medicine is corrupt and low quality. I ran into a lot of gulf state medical tourists in India who told me this (obviously a biased sample).

yummyfajitas··on Difficulties accessing medical services as an EU immigrant in Germany
I've only spent about 6 hours in Germany, so I can't speak about Germany. But in many places - the US and UK, for example - it's often quite difficult to get medical work done simply by paying money.

For example, in the US many doctors refused to treat me - I was later told by a doctor that this is for regulatory reasons. US hospitals are famous for not providing a price before treatment, and often trying to sneak non-insured items onto the bill. Compare the expereinces here (https://www.nytimes.com/2014/09/21/us/drive-by-doctoring-sur... ) with mine (https://www.chrisstucchio.com/blog/2015/medical_tourism.html ).

I've had similar difficulties in the UK - it's mostly NHS or get out of town. (My issues in the UK were minor, so I decided to just wait until I reached India to get them fixed.)
