Re: difference between pdf and accumulative frequency ?

Hi model;

I wish I could help with that but I do not see how Bayes theorem can do what you want.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: difference between pdf and accumulative frequency ?

Or  please mention some useful application where Bayes' distribution is applicable .

Re: difference between pdf and accumulative frequency ?

Hi model;

This is one application of Bayes theorem. It is the best explanation I have seen. I know it is long and gruesome but please read it to get an idea about your question. It has some interesting examples too.

Remember that Bayes theorem can reduced to a formula. Also it is as far away from a Kalman filter as a nail is to building a house.

Re: difference between pdf and accumulative frequency ?

oh thanks i would like to read it .

but  i really want that math is fun site should write some use full practical application of Bayes theorem .

Re: difference between pdf and accumulative frequency ?

also what is the difference  between bayesian and Bayes theorem or filter ?
Are both not same ?

Re: difference between pdf and accumulative frequency ?

oh yes Bayesian is relate to Kalman .
Can we please have  some discussion on Bayesian filter ?

That is difficult to explain, Bayes theorem is a mathematical formula. A Bayesian filter can be an algorithm that uses Bayes theorem. It can be much more complicated or not.

If this sounds tough right now it is because you are not yet familiar with the tools you need to understand it. It is like trying to build a house without knowing how to use a hammer or what a nail is. I can help you with the tools but it will take time.

Please read the page I gave you and then we can discuss it together.

Re: difference between pdf and accumulative frequency ?

How can i use Bayes  theorem for feature  extraction . like recognizing a  hand . ?

Re: difference between pdf and accumulative frequency ?

Hi model;

Good morning. You could use Bayes theorem to figure the probability that the feature you have found is a hand. But it can not do a job as complicated as that by itself.

Did you cover that page? If so, we are ready to start with some examples.

Re: difference between pdf and accumulative frequency ?

Hi I read  out that link .
but please make it fast to complete this .
i want to use Bayes or Bayesian theorem for hand feature extraction.

Re: difference between pdf and accumulative frequency ?

Hi model;

Here is a really easy one. No one woud ever use Bayes for this problem, it is just an example.

What is the probability that the second card of a deck is red if we are told that the first card is black?

P(A) = probability that second card is red.

P(B) = probability that first card is black.

Check this out.
