Offered differently, 2 variables that are independent may not be in certain cases conditionally independent.

They're just not connected at all.

That causes these 2 variables to be conditionally independent.

That is just total probability.

I can drop the 1, and the same is true over here.

Here I simply write 3 dots for the text Perfect Storm.

If you knew this for a fact, then T2 would be independent of T1.

True or false?

So I'm going to be proportional to just the stuff over here.

The first one is straightforward.

You can just take D out of the pool.

Now to tell you the truth for digit recognition of this type, Naive Bayes is not a good choice.

Conditional Styles...

There is a condition attached.

So, as a result, if you know C, whatever counted over here is kind of cut off causally from what happens over here.

We have here a Bayes network, and I'm going to ask you a conditional independence question.

And we learned about conditional independence, in which case we have a Bayes network that looks like this.

Accept cond.

B and C are independent.

So, here's a question.

Accept invitation conditionally

P of not X3 given A, P X2 given A, P X1 given A times P of A.

All I have to do is get an exclusive interview from you.

And second, I export my conditional independence whereby I can omit X1 and X2 from the probability of not X3 conditioned on A.

I'm asking the question whether A is independent of B,

A is conditionally independent of B given E.

A is conditionally independent of B given G.

C and E are conditionally independent based on D, and knowledge of A doesn't change anything.

You already calculated this one before, which is approximately 0.043, and this one over here is 1 minus that, which is 0.957 approximately.

I accept the proposal, but with some reservations.

The house has such a lovely position.

Is F independent of A?

Is F independent of A given D?

Please tell me yes or no.

Is C independent of D?

So you can figure out the answer by intuitive reasoning, or you can figure it out by going to the conditional probability tables and seeing according to the definition of conditional probability whether the numbers work out.

Here's my cancer variable and then there's two conditionally independent tests T1 and T2.

But on one condition. You have to stop lying to me, Mathilda.

A is conditionally independent of B given F, and A is conditionally independent of C given G.
