What we're going to do is run the policy, have a trial that goes through the state when it gets to a terminal state, we start it over again at the start and run it again and we keep track of how many times we visited each state, we update the utilities, and we get a better and better estimate for the utility.

We just found another one. Thought it suffered a little accidental damage.

Each program states consists of several variables with values.

How does the world evolve as we take actions in the world?

So here we have The Plan.

Then the alpha, the learning rate, is 1 2. That gives us 45.

So this shifts to the right, you have a situation where real GDP will go from this state to this state right over here.

And so we'll implement this Path Cost function, in terms of a Step Cost function.

Status Loaded and running.

Here is a diagram of the state space for the vacuum world.

So this volume and that volume.

So it's called a reflex agent because it's pure stimulus response

Here we have a description of a state space.

Shape retaining is common in metal you bend a piece of aluminum foil, and it holds its place.

So we wish to have a planning method that provides an answer no matter where we are and that's called a policy.

Now our belief state contains 2 and 6, and we decide we want to execute the suck action.

So that's actually going to be your definition for live versus dead.

Greater subjective well being.

10 x 6 10 x 2 is 80.

This question involves function generalization in reinforcement learning, and we're operating in a 1 dimensional environment of squares, and we're going to consider a state generalization function, that is a function that takes a state such as this and condenses it into some features to represent that state.

And this is that deflationary cycle that all the economists and all of the government officials are afraid of.

That's what we mean by deterministic, and so that means the size of the belief state will either stay the same or it might decrease if 2 of the actions sort of accidentally end up bringing you to the same place.

I guess the reason we haven't covered it is because I tend to think of it as just another version of search.

So for example a policy might look as follows for this state, we wish to go north, north, east, east, east, but for this state over here, we wish to go north, maybe east over here, and maybe west over here.

Then we would generate something all of us would like to have a balance between the hunger and the satiation.

Let's talk about how to do that.

And that's a type of utility but, rather than being a utility over states, it's a utility of state action pairs and that tells us

In this finite state machine, to go the other direction, and finishing it off by changing the start state with the accepting state.

And that situation cannot be right. We must do something about it.

And suppose for now, every other state costs you 3.

In some problems, the agent will have the same actions available in all states and in other problems, he'll have different actions dependent on the state.

like the one over here and the on over here, have an optimal policy and action associated, because there is really no start state.

Given a particular state we look and see is it a terminal state?

Now let's expand it more, and there's now two options finally

But now, finally for the first time we're going to have an actual update.

In this Unit, we're introducing the third type of learning reinforcement learning in which we have a sequence of action and state transitions.
