Naive Bayes :
About Naive Bayes :
Naïve Bayes algorithm is a supervised learning algorithm, which is based on Bayes theorem and used for solving classification problems.
It is mainly used in text classification that includes a high-dimensional training dataset.
Naïve Bayes Classifier is one of the simple and most effective Classification algorithms which helps in building the fast machine learning models that can make quick predictions.
It is a probabilistic classifier, which means it predicts on the basis of the probability of an object.
Some popular examples of Naïve Bayes Algorithm are spam filtration, Sentimental analysis, and classifying articles.
Formula Of Naive Bayes :
Bayes' theorem is also known as Bayes' Rule or Bayes' law, which is used to determine the probability of a hypothesis with prior knowledge. It depends on the conditional probability. The formula for Bayes' theorem is given as: Naïve Bayes Classifier Algorithm Where,
P(A|B) is Posterior probability: Probability of hypothesis A on the observed event B.
P(B|A) is Likelihood probability: Probability of the evidence given that the probability of a hypothesis is true.
P(A) is Prior Probability: Probability of hypothesis before observing the evidence.
P(B) is Marginal Probability: Probability of Evidence.

To Install the module
pip install naivepy
About Module:
Naivepy module is built using python and pandas. It is and machine learning algorithm. This Module can take the target column and classifies it.
Note : The Target Column must have 2 Types of values other wise MaxTargetColumnException will be occured.
Examples :
Code :
from naivepy import Naive
n=Naive(filename="data.csv",sample_list=["red","suv","domestic"],target_column="stolen")
print(n.getans)
print(n.getdata)
print(n.getlabel)
Output :
Color Type Origin Stolen
0 Red Sports Domestic Yes
1 Red Sports Domestic No
2 Red Sports Domestic Yes
3 Yellow Sports Domestic No
4 Yellow Sports Imported Yes
5 Yellow SUV Imported No
6 Yellow SUV Imported Yes
7 Yellow SUV Domestic No
8 Red SUV Imported No
9 Red Sports Imported Yes
No
