CO2 Emission by Cars

A reliable End to End Machine Learning Model to predict CO2 Emissions in different type of Cars.

Description

The task is to build a machine learning model to predict CO2 emissions by different types of cars based on features such as:

  • Model of car
  • Engine Size (in Litre)
  • Number of cylinders
  • Class of vehicle
  • Fuel consumption (on highways, in city roads)

Project also aims at testing the influence of different independent features on the emission of CO2 using statistical methods.

DataSet:

  • The dataset has been taken from the Canada Government official open data website and is available in kaggle
  • Cleaned and processed version of the data can be accessed from here
  • Dataset contains 7385 datapoints and 12 columns.

Notebook:

Notebook contains the EDA, data processing, and model building ideas.

Models

We experimented with different methods for model building

  • OLS Regression
  • Ridge Regression
  • Lasso Regression
  • Elastic Net Regression

Project Pipeline

Techstack

Python version : 3.7
Packages: pandas, numpy, seaborn, sklearn, mlxtend, statsmodels
Cloud: heroku

Usage [running locally]:

conda create -n envname python=3.7
activate envname
git clone https://github.com/d0r1h/CO2-Emission-by-Cars.git
cd CO2-Emission-by-Cars
pip install -r requirements.txt
python app.py

Results

  • Ridge Regression (with alpha = 0.5) has been the most effective in reducing RMSE.
  • The exact combination of features responsible for high CO2 emissions cannot be predicted Since all the features are highly correlated.
  • Following image shows score table for different models

Inference Demo:

Application is deployed on heroku and can be accessed at https://coemission.herokuapp.com/ and following data can be used to test the application.
