We distinguished deterministic was the casting environments, and we also talked about photos as partial observable.

Male narrator a favorite, a robotic car.

I want to ask you, for each one, which of these properties they exhibit.

For example, SA means we go from S to A.

And in this case, I'm going to keep the location of the agent in the maze observable.

Select objects which are observable on

So any game, for example, where past moves have information about what might be in a person's hand, those games are partially observable, and they require different treatment.

Whereas an environment that's deterministic where the outcome of an action is predictable and always the same.

We just learned about this, using MDPs and value iteration.

Rather I want you to tell me whether it's partially observable.

So, let's see to what extent these expressions make sense to you by going to our next quiz.

Whereas if you need memory, it's partially observable.

And so that's a mathematical formulation of what it means for this plan to be a Goal.

Unknown Station

It will be good to introduce some basic terminology that is commonly used in artificial intelligence to distinguish different types of problems.

The observation partitions the belief state into smaller belief states.

So we now learned about fully observable environments, and planning in stochastic environments with MDPs

Check one or all of those attributes that apply.

An environment is called fully observable if what your agent can sense at any point in time is completely sufficient to make the optimal decision.

An environment is fully observable if the sensors can always see the entire state of the environment.

We've learned about Markov Decision Processes.

Problem solving works when Problem solving technology works when the following set of conditions is true

The environment is clearly stochastic.

It updates the mu and sigma using this recursive formula over here.

Let's contrast this with the case we just learned about, which is the fully observable case or the stochastic case.

And there's another example.

I don't want you to solve the problem, but I want you to answer the following questions

Of course, we know today that galaxies extend far beyond our own galaxy.

Instead, we have a second variable, called B, which is our test, and B is observable, but A isn't.

Narrator We've been considering sensor less planning in a deterministic world.

Multiplied by the speed of light, it gives Hubble length. Which is commensurate with the size of the observable universe.

Physically based rendering is also a great help to virtual world content creators, such as game and film makers.

Almost indescribable, isn't it?

It augments your sense function to have a flag that if it's set to 0 it switches off the noise modeling and gets you the predicted best possible measurements.

The show's too predictable.

But that doesn't affect what we've programed here.

The MDP algorithms which I will talk about first fall into the intersection of fully observable yet stochastic, and just to remind us what the difference was, stochastic is an environment where the outcome of an action is somewhat random.

We didn't have any fancy caching. I just used in memory hash tables.

A scientific theory comprises a collection of concepts, including abstractions of observable phenomena, expressed as quantifiable properties, together with rules (called scientific laws) that express relationships between observations of such concepts.

Okay, let's say this is the size of the observable universe, with all the galaxies, with all the stars, okay, from here to here.

Well it depends on how we operationalize that construct.

I gave you 4 key attributes of intelligent agents (partial observability, stochasticity, continuous spaces, and adversarial natures),
