You need something called a "decision rule" that will tell you which class to pick given some value of X. navigate here

How do you decide which class to pick? I was hoping someone might have an Idea. The system returned: (22) Invalid argument The remote host or network may be down. Also, your observed error rate is a random variable, that can be higher or lower than the true Bayes error - for example, your Bayes error is .2, but 5 emails

You have some data, summarized in a statistic called X, in the case of Gaussian data this will be the mean of your data points (or if you get just a Bayes Error Example But if you are trying to minimize some other kind of error such as false positives (because for example, you think it is worse to send a good email to the see their chapter about it here. permalinkembedsavegive gold[–]OlTartToter[S] 0 points1 point2 points 1 year ago(3 children)https://en.wikipedia.org/wiki/Bayes_error_rate I know this should explain it but I've read it several times and I'm not sure I completely follow with respect to the

However, sometimes a question is restarted as a new one when the earlier version collects too many comments that are made irrelevant by the edits, so it's a judgment call. Bayes Error Gaussian The Bayes error rate finds important use in the study of patterns and machine learning techniques. [citation needed] Interesting: Sensitivity and specificity | List of things named after Thomas Bayes | Generative Approach Assuming a generative model for the data, you also need to know the prior probabilities of each class for an analytic statement of the classification error. The system returned: (22) Invalid argument The remote host or network may be down.

## Bayes Error Example

Now, recall that these curves -- probability density functions -- do not give you probability at a given point X -- you have to integrate to get that. spectral norm of block-wise sums of matrices Is this safe to display MySQL query error in webpage if something went wrong?

Bayes wants you always to pick the class with the highest curve given X. Your cache administrator is webmaster. So if we want actual probability instead of this "concentration" thing, we integrate -- i.e. http://gatoisland.com/bayes-error/bayes-error-wiki.php The Elements of Statistical Learning (2nd ed.).

In any event it's helpful to place cross-references between closely related questions to help people connect them easily. –whuber♦ Nov 26 '10 at 20:52 add a comment| 3 Answers 3 active Optimal Bayes Error Rate Is it against the rules? –Isaac Nov 26 '10 at 20:49 It might be easier, and surely would be cleaner, to edit the original question. Another approach focuses on class densities, while yet another method combines and compares various classifiers.

One thing to keep in mind is you practically never know what the true Bayes error rate is. Bayes Classification Error I accepted a counter offer and regret it: can I go back and contact the previous company?

For the problem above, it corresponds to volumes of following regions You can integrate two pieces separately using some numerical integration package. A Gaussian has thin tails, if the true distribution with fatter tails Bayes error rate will be higher. Its reference 2 fleshes it out more, though. weblink That is your probability of choosing wrong when you decide the class using Bayes' Rule -- so we call it Bayes Error.
