Hi all;

I'm new with this topic and I need some help in my first project.

Now if I have a database in that form:

 pathID   userID      Class

userID is 4000 record  has different numbers starts from (45 to 22300273)

class is only has two value. 0 or 1

now my question is: do I need to make normalisation for the column userId to be able to visulaize the data using Matlab to analyze the data to be able to use Naive Bayes classifier to classify test data for class 0 or 1?

can I have any source code for naive bayes classifier?

Thanks alot
