Using Different Model's

Creating Training and Testing Data set

x_train, x_test, y_train, y_test = train_test_split(X, Y, test_size=0.20, random_state=42)

Training the model using Logistic Regression

model=LogisticRegression()
model.fit(x_train,y_train)

Making the prediction

new_prediction=model.predict(testing_data)

Getting the accuracy score

from sklearn.metrics import accuracy_score


acc_logreg = round(accuracy_score(prediction, y_test) * 100, 2)
print(acc_logreg)

got 86.29 using Logistic regression

Training the model using KNN

model=KNeighborsClassifier(n_neighbors=10)
model.fit(x_train,y_train)

Making the prediction

new_prediction=model.predict(testing_data)

Getting the accuracy score

from sklearn.metrics import accuracy_score


acc_logreg = round(accuracy_score(prediction, y_test) * 100, 2)
print(acc_logreg)

got 88.86 using KNN

Training the model using Decision Tree Classifier

model=DecisionTreeClassifier()
model.fit(x_train,y_train)

Making the prediction

new_prediction=model.predict(testing_data)

Getting the accuracy score

from sklearn.metrics import accuracy_score


acc_logreg = round(accuracy_score(prediction, y_test) * 100, 2)
print(acc_logreg)

got 92.35 using Decision Tree Classifier
