Linear Regression Machine Learning Algorithm

In this ML course tutorial, we are going to learn the “Linear Regression Machine Learning Algorithm in detail. we covered Simple Linear regression and Multiple Linear regression supervised regression learning algorithm by practical and theoretical intuition.

# Business Problem - Predict the Price of Bangalore House
#Using Linear Regression - Supervised Machine Learning Algorithm

### Load Libraries

import pandas as pd

"""### Load Data"""

path = r"" 
df = pd.read_csv(path)


"""### Split Data"""

X = df.drop('price', axis=1)
y = df['price']

print('Shape of X = ', X.shape)
print('Shape of y = ', y.shape)

from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=51)

print('Shape of X_train = ', X_train.shape)
print('Shape of y_train = ', y_train.shape)
print('Shape of X_test = ', X_test.shape)
print('Shape of y_test = ', y_test.shape)

"""### Feature Scaling"""

from sklearn.preprocessing import StandardScaler
sc = StandardScaler()
X_train = sc.transform(X_train)
X_test = sc.transform(X_test)

"""## Linear Regression - ML Model Training"""

from sklearn.linear_model import LinearRegression
lr = LinearRegression(), y_train)



"""## Predict the value of Home and Test"""

X_test[0, :]

lr.predict([X_test[0, :]])



lr.score(X_test, y_test)
