Here is the simple machine learning project in python for beginners, it is actually some machine learning application to predict 2BHK apartment price in a specified city.So first we should explain what is machine learning, it is actually a technique that enable a system to learn from data.In simple it will learn from the data you have given and tell u next data based on the learning.
To do machine learning project in python you have to download anaconda you can download it from the website www.anaconda.com based on python version you can download any of the release.Then double click and install in your sytem.after installing open anaconda and create a new file and name it as myfirstML.py (any name you can give)
SO Lets start coding
1) First we are importing pandas module see code
import pandas
Of course you will ask me what is pandas ,in simple pandas is a library used for data manipulations and analysis.
2) Next assign given data in variable ,we have data of last 10 year price of 2BHK apartment
See below test.csv file
2010,180000
2011,220000
2012,240000
2013,250000
2014,260000
2015,290000
2016,320000
2017,360000
2018,400000
2019,500000
2020,550000
url='test.csv' names=['year','price-for-2BHK']
3) Read CSV with the help of pandas library function
datas= pandas.read_csv(url,names=names)
4) Read CSV with the help of pandas library function
datas= pandas.read_csv(url,names=names)
5) Print data and make sure that we are fecthing data in a variable correctly
print(datas[['price-for-2BHK']])
6) Assign year and price-for-2BHK in respective varibale x and y
x=datas[['year']];
y=datas[['price-for-2BHK']]
7) Import train_test_split and split data using train_test_split
train_test_split is a function in sklearn model selection for spiliting data arrays in to two subsets , for training data and for testing data with this function no need to divide the data manually
from sklearn.model_selection import train_test_split X_train, X_test, Y_train, Y_test =train_test_split(x,y,test_size=0.1,random_state=101)
8) import LinearRegression from sklearn.linear_model
LinearRegression is statistical method used to create a linear model.This model describe the relationship between a dependent variable y as function of one or more independent variable
from sklearn.linear_model import LinearRegression
9) Use LinearRegression() and fit method
LinearRegression is statistical method used to create a linear model.This model describe the relationship between a dependent variable y as function of one or more independent variable
model= LinearRegression() model.fit(X_train,Y_train)
10) Finally predict the price based on the year
print(model.predict([[2030]])) Output 2BHK price in 2030 :855446.85990338

import pandas

datas= pandas.read_csv(url,names=names)
print(datas[['price-for-2BHK']])
x=datas[['year']];
y=datas[['price-for-2BHK']]
from sklearn.model_selection import train_test_split
X_train, X_test, Y_train, Y_test =train_test_split(x,y,test_size=0.1,random_state=101)
from sklearn.linear_model import LinearRegression
model= LinearRegression()
model.fit(X_train,Y_train)
print(model.predict([[2030]]))
