So state and action, state and action and so on.

The Step Cost function takes a state, an action, and the resulting state from that action and returns a number n which is the cost of that action.

We apply that 45 to the state action pair.

I happen to know in the goal state that the action was a down action.

I'm in a certain state, I take a certain action.

So I associate the action with the successive state not with the originating state over here.

Then the action that the agent would take would be just to take the action that results in the maximum state the state with the best value.

We have a transition function that tells us the result of, in some state, applying an action giving us a new state.

So I find the originating state by taking my current state and subtracting the action exactly the same way I added it before using my action field as finding out what action was actually being used.

Then the value of the state for the action go up would be obtained as follows.

The probability of reaching S prime given that we started state S and apply action A.

In each case, we'd be updating only the action we took, associated with that state, not the whole state.

A piece of the action. What action?

Suffixes, 1 ion creates nouns that show the meaning of 'action, state, process, results,' and so on.

These are used to describe what happens in the state that's a successor of executing an action.

It's continuous in its state and action spaces and its measurement, yes or no?

If we have a predicate Possible of A and S, is an action A possible in a state?

So for each state, I've divided it up into different actions so here's the action of going north, south, east or west from this particular state.

So, for example, if the agent is in the city of Arad, and takes that would be the state and takes the action of driving along Route E 671 towards Timisoara, then the result of applying that action in that state would be the new state where the agent is in the city of Timisoara.

This belief state with 4 possible world states, and if I then execute the right action, followed by the suck action, then I end up in this belief state, and that satisfies the goal.

Inertia, lack of action.

That is, if I execute the east action of this state over here with probability 1 item over here, if I assume the north action over here, probability 1,

We were in this state, and we executed the action north, so the 45 goes here.

Next we have a function called Result, which takes, as input, a state and an action and delivers, as its output, a new state.

So the prediction step is when we start off in a belief state we look at the action, we look at each possible result of the action because they're stochastic to each possible member of the belief state, and so that gives us a larger belief state and then we update that belief state by taking account of the observation and that will give us a smaller or same size belief state.

If that's true, then the In predicate holds between some cargo C and some plane in the state, which is the result of executing action A in state S.

There's a specific form for describing these predicates, and in general, it has the form of some precondition of state S implies that it's possible to do action A in state S.

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

For any given state and any given action, what's the utility of that result without knowing the utilities and rewards, individually?

State of Matter

So the planning problem is now the problem which relies on an action to each possible state.

Well, it's just the sum over all resulting states of the transition model the probability that we get to that state, given from the start state, we take an action specified by the optimal policy times the utility of that resulting state.

We have fully observable with a set of states and corresponding actions where they have stochastic action effects characterized by a conditional probability entity of P of S prime given that we apply action A in state S.
