Coronavirus:The Lost 6 Weeks America Wasted

JiggaJonson says...

What a fucking dumb analogy. WASTED BREATH


Can i get suicide if I bump into someone suicidal at the grocery store?

If I'm accidentally poisoned, should I worry about giving it to everyone at the office?

If my grandma breaks her hip and falls down the stairs, can I care for her and not put my child and wife at risk?

If I have the flu, and everyone around me has a current flu vaccination, should I treat it the same way I would COVID 19?

Perspective

Multi-Agent Hide and Seek

L0cky says...

This isn't really true though and greatly understates how amazing this demo, and current AI actually is.

Saying the agents are obeying a set of human defined rules / freedoms / constraints and objective functions would lead one to imagine something more like video game AI.

Typically video game AI works on a set of weighted decisions and actions, where the weights, decisions and actions are defined by the developer; a more complex variation of:

if my health is low, move towards the health pack,
otherwise, move towards the opponent

In this demo, no such rules exist. It's not given any weights (health), rules (if health is low), nor any instructions (move towards health pack). I guess you could apply neural networks to traditional game AI to determine the weights for decision making (which are typically hard coded by the developer); but that would be far less interesting than what's actually happening here.

Instead, the agent is given a set of inputs, a set of available outputs, and a goal.

4 Inputs:
- Position of the agent itself
- Position and type (other agent, box, ramp) of objects within a limited forward facing conical view
- Position (but not type) of objects within a small radius around the agent
- Reward: Whether they are doing a good job or not

Note the agent is given no information about each type of object, or what they mean, or how they behave. You may as well call them A, B, C rather than agent, box, ramp.

3 Outputs:
- Move
- Grab
- Lock

Again, the agent knows nothing about what these mean, only that they can enable and disable each at any time. A good analogy is someone giving you a game controller for a game you've never played. The controller has a stick and two buttons and you figure out what they do by using them. It'd be accurate to call the outputs: stick, A, B rather than move, grab, lock.

Goal:
- Do a good job.

The goal is simply for the reward input to be maximised. A good analogy is saying 'good girl' or giving a treat to a dog that you are training when they do the right thing. It's up to the dog to figure out what it is that they're doing that's good.

The reward is entirely separate from the agent, and agent behaviour can be completely changed just by changing when the reward is given. The demo is about hide and seek, where the agents are rewarded for not being seen / seeing their opponent (and not leaving the play area). The agents also succeeded at other games, where the only difference to the agent was when the reward was given.

It isn't really different from physically building the same play space, dropping some rats in it, and rewarding them with cheese when they are hidden from their opponents - except rats are unlikely to figure out how to maximise their reward in such a 'complex' game.

Given this description of how the AI actually works, the fact they came up with complex strategies like blocking doors, ramp surfing, taking the ramp to stop their opponents from ramp surfing, and just the general cooperation with other agents, without any code describing any of those things - is pretty amazing.

Another entrant in the incredibly long line of adaptation / adaptive learning / intelligent systems / artificial intelligence demonstrations that aren't. The agents act based on a set of rules / freedoms/constraints prescribed by a human. The agents "learn" based on the objective functions defined by the human. With enough iterations (how many times did the narrator say "millions" in the video) . Sure, it is a good demonstration of how adaptive learning works, but the hype-fog is getting a big thick and sickening folks. This is a very complex optimization problem being solved with impressive and current technologies, but it is certainly not behavioural intelligence.

It's Not Okay

greatgooglymoogly says...

Actual racists only use these new symbols when the mainstream recoils in horror and labels the trolls incorrectly as racists instead of as trolls, or just ignoring them. I think many spreading the "it's ok to be white" slogan are trolls too. They enjoy seeing people freak out at a phrase that says nothing negative about anyone, but many people will read into it a hidden meaning. You can't discern intention in these cases, only assume based on your personal previous exposure. I seem to understand it as a response/analog to "black lives matter" which most people don't think secretly means white lives don't matter, and the posters think the disproportionate response is racial bias.

newtboy said:

I agree with not accepting their usurping common terms and gestures, but I cannot accept ignoring what them mean by them. Just because I don't mean anything racist when I use the OK hand symbol, I'm not going to pretend the white supremacist assholes flashing it behind the black sports announcer wasn't blatantly a racist move. Thankfully, neither are the stadium owners who banned those people for life.
Recognizing their racist intentions is not the same as condoning their racist usurpation of language. Ignoring their racist meaning and usage is condoning it. I will call them out when I think they're being racist, which these people undeniably are. "It's ok to be white" is a slogan used EXCLUSIVELY as a racist taunt, not a factual statement of equality.

Don't ignore racism in an effort to deny it power, that doesn't work....it only allows it to fester and grow. Bright sunlight is the best disinfectant.

Why This Anesthesiologist Quit

newtboy says...

Know who you take advice from....
Just gonna leave this here....

Wiki-
Dr Michael Klaper-In August 1993 Klaper issued a medical certificate for the insurers of two movies that River Phoenix was working on at the time, Dark Blood and Interview With the Vampire. The certificate was signed by both Klaper and Phoenix and stated that Phoenix had never used "LSD, heroin, cocaine, alcohol in excess, or any other narcotic, depressant, stimulant or psychedelic. At the time Phoenix was deeply into the drug scene and died from a drug overdose two months later on October 31, 1993. Phoenix's death resulted in Dark Blood being scrapped, and his role in Interview with the Vampire being replaced by Christian Slater. A total $US5.7 million was paid out by the insurers of both movies as the result of Phoenix's death. Since Phoenix's death, insurance rates have increased significantly, medical certificates are no longer accepted, and actors are required to undergo more rigorous medical examination prior to being insured. [23]

According to oncologist David Gorski "Klaper subscribes to the all-too-common claim that a vegan diet is better than any other and supplements that claim with a belief that undergoing fasts, in which one consumes only water, is a major part of the path to health and wellness". He supports multiple pseudoscience medical claims such as acupuncture, chiropractic, naturopathy and border-line "germ theory denialism". Klaper also gives "highly dubious advice for cancer patients, even claiming that fasting can shrink malignant tumors. Klaper claims that fasts will clear up inflammation, eczema, arthritis and other issues. "The situation" according to Gorski, is "way more complicated than Dr. Klaper paints it". As a surgeon himself, Gorski is appalled that Klaper claims that fasting encourages "faster wound healing" a statement that Gorski calls "Bullshit!". Magician Penn Jillette reported on multiple podcasts that he has lost over 25 pounds on Klaper's water fast diet, Gorski responded that of course he will lose weight on a water-only diet. In Gorski's opinion as a medical doctor himself, "Jillette has fallen "hook, line, and sinker for a whole lot of dietary pseudoscience and promoting it on his show with a credulous interview with someone like Dr. Klaper". Gorski hopes that Jillette will eventually realize "that Dr. Klaper is peddling highly dubious claims (at best). Basically, the product Dr. Klaper is peddling in terms of science is a massive exaggeration based on dubious science, cherry picked cases, and bad evolutionary analogies. Worse, fasts, even when supervised by a physician, are potentially dangerous"

Racist Australian Senator egged by hero kid

transmorpher says...

Typical lefties, screaming racism where there is none (Religion is not a race) and becoming uncivil because they aren't capable of disproving factual claims.

This is Charles Murray at Middlebury College all over again. Thankfully this time nobody got injured when the lefties lashed out.

Once again lefties do not understand a nuanced subject so they cling to moral outrage which quickly escalates to violence when they don't get their way - silencing free speech.

The senator was not blaming muslims for the attack, he specifically said there is no justification for the attack, and CONDEMNED THE ATTACK. He was saying that lefties are silencing free speech, and that in turn radicalizes right leaning people - which is a problem, because the last thing the world needs is right leaning people being radicalized into full blown racists - because nobody is allowed civil discourse, which divides people into extremes.

And this egging is a perfect analogy for the problem the senator was describing.


-----

The lefties have got people so scared to have civil discourse about immigration, integration and other similar issues that the only people not afraid to talk about it are genuine racists. This is a huuuuuuuuuuuge problem. And as a centrist, this frustrates me to no end, because I have racists on one side of me, and lefty fascists on the other - both of which foaming at the mouth.

A Better Way to Tax the Rich

newtboy says...

Yes, widespread poverty, largely because of insane wealth inequality. (I'll elaborate if you wish) The rich had plenty to eat, and as the dismissive "let them eat cake" implied, had no concern for those who didn't. It was that disparity paired with the dismissal of the peasants plight by the ruling class that tipped a bad situation into civil war/revolt, imo.

Yes, poor are going hungry in the United States, maybe not starving to death often, but suffering to death from ailments caused by the only diets they can afford, which barely qualify as food. No, it's not to the extent of 1700 France, but we wouldn't tolerate anywhere near those conditions today, so that argument is ludicrous.

The real poor in America don't have roofs or electricity, where are these TV'S they're parked in front of exactly? The homeless problem is growing exponentially...those are the real poor surfs in this analogy, not just people like me who can live fine on $15k a year.

dogboy49 said:

Yes, I have heard of the French Revolution. You seem to imply that the main cause was wealth inequality, but you have not offered any reason as to why you think that.

Many believe that the biggest contributor to the French Revolution was widespread poverty. Peasants were starving.

This condition does not exist today. Especially in the US, the poor are not suffering in the same way they were in France in the mid 1700's.

In France, it was necessary to riot in order to eat. Today's poor in the US have a hard time getting up from their TV sets.

Paranoid and pissed off
Now that I got the money
Fifty acres and a model A
Right in the middle of Trump country
I told you there goes a neighbourhood
Now mister Williams ain't so funny
I see you looking out your window
Can’t wait to call the police on me
When I know you think I'm up to somethin'
I'm just eating out but still hungry
And this is my analogy
I ain't even near you can't take it from me
I remember when you used to tell me
'Nigga run, nigga run
Go back where you come from
Nigga run, nigga run
Go back where you come from
We don't want, we don’t want your kind
We think you’s a dog born
Fuck you, I'm America’s son
This is where I come from
This land is mine
This land is mine
This land is mine
This land is mine
Up till the sun comes up
No I can't stop grindin'
And I can't let ’em break me
No I can't let 'em find me
You can meet my friend the governor
Only if you wanna try me
Or you can meet my other friend the judge
Just in case you think I'm lyin'
And I know you think I'm up to somethin'
I'm just eating out but still hungry
And this is my analogy
I ain't leaving here you can't take it from me
I remember when you used to tell me
'Nigga run, nigga run
Go back where you come from
Nigga run, nigga run
Go back where you come from
We don't want, we don't want your kind
We think you's a dog born
Fuck you, I'm America's son

We Believe: The Best Men Can Be - Gillette Ad

Mordhaus says...

I'm sure they will gain more overall customers because they are owned by Proctor & Gamble. As I mentioned originally, there will be plenty of women and white knights who jump at the chance to support a company who decided to tag along onto the #metoo movement.

To me, that is part of the reason why I dislike this commercial so much. Not just because of it's huge and sweeping generalizations (practically every scene has one), but because their ad department had to know that an edgy commercial would do the same thing for them as it did for Nike. Does anyone think that the majority of actual corporate level people at Gillette/P&G give two fucks about #metoo? I know I don't.

It's just an ad targeted at a huge group of people that are easy to take potshots at currently. I find it little different than attack ads run by fucktards that want to condemn all Muslims for the act of terrorists or fundamentalist jihadists. The most screwed up thing about that analogy is that, realistically, there are largish groups of Islamic people that actually will cheer and throw celebrations when there is a terrorist attack. Yet you would be hard put to find large swaths of men out in the streets cheering on the effects of so called Toxic Masculinity.

Yes, we as men need to speak out. We need to support the evolution of mankind away from barbarism. But we don't need to succumb to propaganda that tries to purport that a man seeing a pretty lady walk past shouldn't attempt to say hi or introduce himself to her because that is bad. This ad, with one of the sweeping generalizations I mentioned earlier, would have you think that it is HORRIBLE for a man to do that and that a 'responsible' man would body check that guy. Because men should never try to meet women, only remain passive and allow the woman to come to them. I say fuck that, it is wrong to catcall women, but there is nothing wrong with going up and saying hi. This ad (and some other internet videos) would have you think it's the equivalent of throwing the lady down in the middle of a crowded walkway and having your way with her.

The ad could have been better, there were moments like the Terry Crews scene that I agree with, but they took the easy way out and just slammed men in general.

newtboy said:

Gillette is betting on the theory that they will gain far more new customers than they lose over this.....just like Nike using Kaepernick. It worked for Nike despite the over the top vocal outrage and videos of burning $500 sneakers, I think Gillette expects similar results.

Can This Change Everything for DJs

ChaosEngine says...

I have questions.

Maybe I missed it, but I feel like they didn’t really explain what it is or how it works.

I guess it’s some kind of replacement for a record needle, that uses an accelerometer(?) or something, but I’d really like more details.

Also (and I know nothing about DJing, so tell me if I’m being an idiot), surely using this kind of digital wireless thing (again not sure how it works) would defeat the purpose of using analog vinyl in the first place?

A Scary Time

BSR says...

Thanks for your reply bcglorf,

To clear up my analogy, I was actually speaking about the power, tolerance and bravery of women and the thick headedness and cowardice of men who are abusers.

Sometimes you need to find a language that can be understood.

I also think reasonable people believe that any action taken against them should be met with equal and opposite reaction.

Somewhere I posted a quote from the movie Tora, Tora, Tora, which I altered to fit the present conversations.

The quote was said to have been made by Japanese Admiral Isoroku Yamamoto regarding the 1941 attack on Pearl Harbor.

It's debated if he actually said it but it was something that I remembered and thought it fit well with recent events with the altered quote.

My altered quote is:

I fear all we have done is to awaken a sleeping giantess and fill her with a terrible resolve.


Women (giantess) are coming together, along with men, more than ever before and rightly so.

I never said or implied anything about ridicule or attacks.

Thanks again for your reply and I think we both are on the same side.

bcglorf said:

Not sure that's the analogy you want to go for, what with the counter being to describe how we behave once we grow up...

You are describing women as powerless and perpetual victims, which I think is offensive to women. You then basically say that two wrongs make a right because victims should be allowed to create new victims if it helps them...

Reasonable people disagree with you. If that puts me in the 'wrong' camp, and means I deserve ridicule and attack, you're the problem, not me.

When an infant or child needs something but can't or doesn't know how to communicate it's needs, they will make their problem your problem. They do this by crying or acting out until they get what they need, be it a diaper change or a glass of water or just a hug.

Women have been trying to communicate for eons with little results. Now they are making their problem, your problem.

You may be able to look to them for bravery if that's what you're lacking.

Teacher Fed Up With Students Swearing, Stealing, And Destroy

JiggaJonson says...

I disagree. Pinpointing the problem isn't very hard if you have some idea of where to look.

As someone who was 'coming of age' in my profession when No Child Left Behind (NCLB) and its successor the Every Student Succeeds Act (ESSA), I can provide some insight into how these policies have been enacted and how both have been detrimental to the public education system as a whole. The former is a GWBush policy, and the latter is an Obama policy meant to mend the original law, so both liberals and conservatives are to blame to some degree, but both are based on the same philosophy of education and teacher-accountability.

There are some other mitigating factors and outside influences at work that should be noted: gun violence, the rise & ubiquity of the internet, and universal cell phone availability, all mostly concentrated in the past 10 years that play a large role. Cell phones, for example, are probably the worst thing to happen to education ever. They distract, they assist in cheating, they perpetuate arguments which can lead to physical altercations, and parents themselves advocate for their use "what if there's an emergency?!?!"

The idea of "teacher accountability" is the biggest culprit though.

Anecdotally, I've caught people cheating on papers. A girl in my honors English class basically plagiarised her entire final paper that we worked on for close to a month. The zero tanked her grade, which was already floundering, and the parent wanted to meet. I'd rather not go into detail to protect both the girl and my own anonymity, but suffice to say, all of the blame for this was aimed directly at me. How? Well I (apparently) "should have caught this sooner and intervened." Now, the final in that class is 8 pages long, I have ~125 students all working on it at the same time. but my ability to check something like that and my workload are beside the point. I'M NOT THE ONE WHO COPY PASTED A WIKIPEDIA ARTICLE AND DOCTORED IT UP SO IT COULD SQUEAK BY THE PLAGIARISM DETECTOR (shows she knew what she was doing, IMHO). Yet, I'm still the one being told that I was responsible for what happened.

Teacher-accountability SOUNDS like the right thing to do, but consider the following analogies

--Students are earning poor grades, therefore teachers should be demoted; put on probationary programs; lose some of their salaries; and if they do not improve their test scores, grades, and attendance; be terminated from their positions.

as to

--Impoverished people have poor oral hygiene/health, therefore their dentists should be forced to take pay cuts from insurance companies. If the patients continue to develop cavities and the like, the dentist should be forced to go for further training, and possibly lose his practice.

I have no control over attendance.
I have no control over their home life.
I have no control over children coming to school with holes in their shoes, having not eaten breakfast.

@Mordhaus the part about money grubbing could not be further from the truth.

I'll be brief b/c I know this is already too long for this forum, but Houton Mifflin, McGraw Hill, Etc. Book Company is facing a shortfall of sales in light of the digital age. It may be difficult to blame one entity, but that's a good place to start. They don't sell as many books, but guess who produces and distributes the standardized tests and practice materials? Those same companies who used to sell textbooks by the boatload.

When a student does poorly, they have to retest in order to recieve a diploma. $$$ if they fail again, they retest again and again there is a charge for taking the test and accompanying pretest materials. Each of which has its own fees that go straight to the former textbook companies. See: https://www.pbs.org/wgbh/pages/frontline/shows/schools/testing/companies.html

In short, there is an incentive for these companies to lobby for an environment where tests are taken and retaken as much as possible. Each time a student has to retest that's more $ in their pocket.

How can they create an enviorment that faccilitates more testing? Put all the blame on the educators rather than the students.

That sounds a little tin-foil-hat conspiracy theory-ish, but the lobbying they do is very real: https://www.washingtonpost.com/news/answer-sheet/wp/2015/03/30/report-big-education-firms-spend-millions-lobbying-for-pro-testing-policies/?utm_term=.
9af18f0d2064

That, combined with exceptions for charter/private schools where students have the option to opt-out of said testing is skewing the numbers in favor of all of these for-profit companies: http://sanchezcharter.org/state-testing-parent-opt-out/ << one example (you can't opt-out in a public school, at least in my state)

@bobknight33 idk if i'd call business-minded for-profit policies "liberal"

Mordhaus said:

Instead of focusing on who 'created' the problem, which I guarantee you cannot tie to any one specific group or ideology, we should be instead looking for a solution to the problem.

At some point we are going to have to quit beating our drums about 'bleeding heart' liberals or 'heartless money grubbing' republicans and work together. If we can't, then we deserve everything we have coming.

MagLev Trains Pass At 700 km/hour (434.96 mph)

BSR says...

Stop the video at 1:09 and then tap the period key to advance frame by frame. I believe it's the repeating design of the train and the sync of the video that causes the illusion. Camera vs naked eye is like digital vs analog. Pattern vs blur.

BTW, put some underwear on your eyes, please.

DataSchmuck said:

There's a weird ripple effect going on in the top left corner of the window when it passes. Can anyone explain what that is? I'm guessing something to do with frame-rate of the camera vs speed of the passing train? Or would you see it with the naked eye?
