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.

Is this a Parody of the previous videos which Judge cheese, wine, and scotch, because this is Yogurt. YOGURT people, No one cares or judges this stuff.
It's not a fine food.

Why should some one work hard supplement someone who didn't work hard or tried hard and came up short?


Swap out "GPA" with "Hard Earned Money" and these people are capitalists 100%!


Also higher education shouldn't be funded with tax dollars.

What does Trump have to do with this? His dad paid for his schooling and gave him $ to start his life on. He did not squandered the $. And you look at this as evil or such?

You want all to be dependent on government cheese or self sustaining?

American Government programs are 1 thing. Socialism as the main form of government is another.

I think they could take sesame seeds off the market and I wouldn't even care. I can't imagine 5 years from now, saying, "Damn, remember sesame seeds? What happened? All the buns are blank! They're gonna have to change that McDonald's song: 'Two all-beef patties, special sauce, lettuce, cheese, pickles, onions, on a... bun.' How's a sesame seed stick to a bun? That's fuckin' magical! There's got to be some sesame seed glue out there! Either that, or they're adhesive on one side. "Take the sesame seed out, remove the backing, place it on the bun. Now your bun will look spectacular." What does a sesame seed grow into? I don't know, we never gave them a chance! What the fuck is a sesame? It's a street...it's a way to open shit!

That's odd, I make an entirely different sound when I cut the cheese.....

Seems a bit odd that they don't mention the reason Mount Athos is recently famous -- females, including even female animals, are banned. I guess they import all their cheese.

It's pretty clear the governments can't get their shit together, so it is up to us as individuals to drive the change.

If you want to do your part to combat climate change, then any reduction in products that come from animal farming is going to decrease your carbon (and methane) foot print.

e.g. Go for the bean burrito with guac or tahani dressing, instead of a beef and cheese burrito.

Go for the coconut/soy/almond ice cream instead.

Teaching them to take our cheese-searching jerbs!

Forget elevators, the videos of escalator failures are terrifying.

You expect to laugh at the out of order escalator sign because oh no, now they are normal stairways, then the reality is that catastrophic escalator failure is human cheese grater mode..
