Test for Naive Bayes Classifier

In Mitchell, p.71, we see a table related to the "Play Tennis" problem. In p.190 we are given the instance ['Sunny', 'Cool','High','Strong']. We are then ask to predict if it should to play tennis or not (to classify the instance).

First of all, we implement the table of page 71:

import pandas as pd

d = {'Outlook':['Sunny','Sunny','Overcast','Rain','Rain','Rain','Overcast','Sunny','Sunny','Rain','Sunny','Overcast','Overcast','Rain'],
     'Temperature':['Hot','Hot','Hot','Mild','Cool','Cool','Cool','Mild','Cool','Mild','Mild','Mild','Hot','Mild'],
     'Humidity':['High','High','High','High','Normal','Normal','Normal','High','Normal','Normal','Normal','High','Normal','High',],
     'Wind':['Weak','Strong','Weak','Weak','Weak','Strong','Strong','Weak','Weak','Weak','Strong','Strong','Weak','Strong'],
     'PlayTennis':['No','No','Yes','Yes','Yes','No','Yes','No','Yes','Yes','Yes','Yes','Yes','No']}
df = pd.DataFrame(data= d)   
df  

Such dataframe can be seen below:

Outlook	Temperature	Humidity	Wind	PlayTennis
Sunny	Hot	High	Weak	No
Sunny	Hot	High	Strong	No
Overcast	Hot	High	Weak	Yes
Rain	Mild	High	Weak	Yes
Rain	Cool	Normal	Weak	Yes
Rain	Cool	Normal	Strong	No
Overcast	Cool	Normal	Strong	Yes
Sunny	Mild	High	Weak	No
Sunny	Cool	Normal	Weak	Yes
Rain	Mild	Normal	Weak	Yes
Sunny	Mild	Normal	Strong	Yes
Overcast	Mild	High	Strong	Yes
Overcast	Hot	Normal	Weak	Yes
Rain	Mild	High	Strong	No

The instance can be coded as:

instance = ['Sunny', 'Cool','High','Strong']

Since I already coded the Naive Bayes Classifier, we just need to apply it:

classificacao = naive_bayes(df, instance)

As we can seen, the answer is 'N'o
