Garbage can crash

TheFreak says...

Looks like someone's about to get an HOA violation for an improperly placed trash receptacle. This is 3 strikes, after the fine for the lawn being longer than 1.25 inches and the infamous "paper cup on the driveway" incident.

House Robbery In Suburbia Goes Terribly Wrong.

Well, being bald I can't dye my own. ;-)

I think I probably learned it when looking at house paint colors. Not my cup of tea, but I suppose it's a better color than puce.

I don't know, but I'm curious where you learned the name of that color from? That's no crayola color. I'm just gonna imagine you dye your wifes hair

Trump Impeached

newtboy says...

Please don't misconstrue my abhorrence of today's republican party as an endorsement of the democratic party....but there's no question which is worse imo. I've said for decades that I would vote republican if only they would. I didn't leave the republican party, it left me.

'They weren't the only ones sticking it to democrats' isn't an argument, defense, or excuse...it's a dodge imo. Americans are allowed to participate in political propaganda (if they do it legally), other nations aren't. Russian intelligence hacked democrats at Trump's public request to help him. Period.

As for who is G2, "Working off the IP address, U.S. investigators identified Guccifer 2.0 as a particular GRU officer working out of the agency’s headquarters on Grizodubovoy Street in Moscow."

I totally agree citizens United (i mean the court ruling bearing that name) put a poison pill in all of our political cups. I would support any candidate who I believed would make a constitutional amendment fixing that priority one, for any and every office high to low. Sadly i don't know of one from any party.
Selling our political system to corporations and billionaires can only end in it's demise.

it wasn't the Russians that leaked to Wikileaks that the Clinton campaign rigged the election campaign, it was an internal staffer that was pissed in 2016. The second so called hack of Podesta's emails by fishing by G2 we dont know the origin yet. but we do know the first leak in the election to wikileaks came from a staffer in the DNC to report on rigging.

Michael Knowles Calls Greta Thunberg Mentally Ill

newtboy says...

What a disgusting piece of shit and outright liar.
Her achievements already outweigh his by miles...he's only managed to get himself kicked off Fox, impressively hard to do if you're right wing. Fox has apologized for his disgraceful ad hominem attacks against a child who he couldn't factually contradict....but Laura Ingram has also personally attacked her on her show, as has Trump on Twitter.

Being on the autism spectrum, she says she has aspergers, is a developmental disorder NOT a mental illness.
Being a pathological liar, that's a mental illness apparently now shared by an entire political party.
Being a fecal golem is a personality disorder he clearly has in spades.

The Carnegie Mellon study he sites said no such thing, and it's authors have stated that it's a total misrepresentation of their findings....repeatedly.
The study actually said certain produce at it's worst might be more ecologically harmful per calorie than some kinds of white meat eating by comparing things like bacon vs lettuce on a calorie to calorie instead of serving to serving rate, so 4 strips of bacon were compared to > 40 cups of lettuce. Get real.
To compound the confusion they chose a calorie poor produce like lettuce with high greenhouse gas emissions instead of kale, broccoli, rice, potatoes, spinach and wheat (just to name a few) which all rank lower than pork in terms of greenhouse gases.
The same argument holds for water usage...they chose lettuce, with high water requirements, instead of things like corn, peanuts, carrots and wheat which all use less water than all non-seafood meat.
It's also assumed the produce will be wasted at exponentially higher rates than meat, which can be preserved more easily. That may be true, but they don't include the preservatives or energy to refrigerate and/or freeze meat on the bacon side of the equation.

Of course the lettuce takes more resources if you eat 40+ cups instead of 4 thin bacon strips, just like when you compare a single fish stick to several giant pumpkins.

*rant over*

Multi-Agent Hide and Seek

bremnet says...

Thanks for the link and the education, truly appreciated. I'm still stuck on "there has to be more to it" ... but I guess after 85 million games, the outcome is bound to be a winner. Same philosophy I have for the Leafs winning the Cup.

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.

You can find out more about how the agents were trained, and other exercises they performed here:

60 teens vandalizing and looting Walgreens

BSR says...

If they have their cup out they probably already have something in it. If I don't see someone more downtrodden, it goes in the cup.

Are you asking me to send you a check?

BTW, I only give the idea as an example. You know, baby steps.


newtboy said:

Then why ignore the one asking for help to give to one who just looks like they need help? That's not trust, it's judgement. Maybe they're just dirty, not homeless or needy.

60 teens vandalizing and looting Walgreens

BSR says...

File that under the "Thoughts and Prayers" column. It does nothing.

Try this sometime. While you are riding around in your car and happen to see a black homeless person, pick one that's not holding out a cup. Someone that's not expecting it and give him or her $20 bucks and drive away. It will fill your heart and theirs. Watch their face in your rearview mirror. You will feel like you saved the world and you never spoke a word.

WOW, he's ready to go pro. Got the waterworks flowing and everything. Now you just need to teach him to do that when an opposing player's shadow crosses his and he'll be World Cup material.
