These details are Gender, Marital Status, Education, Number of Dependents, Income, Loan Amount, Credit History and others. To automate this process, they have provided a dataset to identify the customers segments that are eligible for loan amount so that they can specifically target these customers.

Answer 2

import pandas as pd

import numpy as np

import seaborn as sns

import matplotlib.pyplot as plt

import sklearn

df=pd.read_csv("/content/train_ctrUa4K.csv")

df.head(10)

df.shape

df.dtypes

df.corr()

a= df['Property_Area'].values

df.isnull().sum()

from sklearn.preprocessing import LabelEncoder

le=LabelEncoder()

df.Property_Area=le.fit_transform(df.Property_Area)

df.Property_Area.head(20)

df.Loan_Status=le.fit_transform(df.Loan_Status)

df.Loan_Status.head(20)

newdf=df.replace(np.NAN,{'LoanAmount':100,'Loan_Amount_Term':360.0,'Credit_History':1.0})

newdf

newdf.isnull().sum()

sns.relplot(x='ApplicantIncome',y='LoanAmount',hue="Credit_History",data=newdf)

x=newdf.drop(['Loan_ID','Gender','Married','Dependents','Education','Self_Employed','Loan_Status'],axis='columns')

print(x)

y=newdf['Loan_Status']

print(y)

from sklearn.model_selection import train_test_split

print(len(x_train))

print(len(x_test))

from sklearn.tree import DecisionTreeClassifier

clf=DecisionTreeClassifier(random_state=5)

clf.fit(x_train,y_train)

y_pred=clf.predict(x_test)

y_pred

from sklearn.metrics import accuracy_score

Accuracy=accuracy_score(y_test,y_pred)

print("Accuracy is",Accuracy*100,'%')

from sklearn.metrics import confusion_matrix

cm=np.array(confusion_matrix(y_test,y_pred))

cm

from sklearn import tree

tree.plot_tree(clf)

plt.figure()

tree.plot_tree(clf,filled=True)
