# Any Naive Bayesian Classifier in python?

this one helps. The scikit-learn has an implementation of Gaussian naive Bayesian classifier. In general, the goal of this library is to provide a good trade off between code that is easy to read and use, and efficiency. Hopefully it should be a good library to learn of the algorithms work.

## Which should be the list of ignored words for the Naive Bayesian Classifier?

By : Semra Khan

wish help you to fix your issue You would be dealing with a lot of words .... mostly Adjective and Conjunctions and maybe verbs ....
Its a very long list you need to save as txt or import to your database ..... I suggest you just google and download directly

## Understanding of ROC Curve applied to Naive Bayesian Classifier python

around this issue Receiver operating characteristic (ROC) is used for illustrating the performance of a binary (two class) classifier. So you would have to restrict yourself to two classes (X vs. Y or X vs. not X) for a single curve (but you can repeat generating a curve for other pairs of classes).
Instead of finding the class C for which -log prob(C|O) is minimal, you would use the values prob(C1|O) (assuming that they are normalized the same way between rows of your data sample).

## How should I go about writing a naive Bayesian classifier in Python?

seems to work fine The nltk.classify.naivebayes module may be what you're looking for. Here is a page with examples of how to use nltk classifiers. It shows how to classify text, but should provide some hints as to how to train a classifier based on your weather features.

may help you . You can begin with Markov Model. In Markov Model you assume that probability of each state is given only by the previous state. For example in a series like 000111100111 you get following transition occurrences:

## Accurancy of Naive Bayesian classifier?

may help you . Normally in machine learning one would look at specificity vs. sensitivity to access the performance of the classifier. http://en.wikipedia.org/wiki/Sensitivity_and_specificity
Since there is normally a trade of between true positives, false positives, true negative and false positives, it is important to decide what is more important in the particular application that you are looking at.
