  3. INTRODUCTION In this particular presentation we will be looking on:  From a long time since being, a continuous paradigm of transactions of commodities has been into existence. Earlier these transactions were in the form of barter system which later was translated into a monetary system. And with consideration into these, all changes that were brought about the pattern of re- selling items was affected as well. There are two ways in which the re-selling of the item is carried out. One is offline and the other being online.  In offline transactions, there is a mediator present in between who is very vulnerable to being corrupt and make overly profitable transactions. The second option is online wherein there is a certain platform which lets the user find the price he might get if he goes for selling.
  4. OBJECTIVE To build a supervised machine learning model for forecasting value of a vehicle based on multiple attributes. The system that is being built must be feature based i.e., feature wise prediction must be possible. Providing graphical comparisons to provide a better view.
  5. MOTIVATION AND CHALLENGES  The automotive industry is composed of a few top global multinational players and several retailers. The multinational players are mainly manufacturers by trade whereas the retail market features players who deal in both new and used vehicles  The used car market has demonstrated a significant growth in value contributing to the larger share of the overall market. The used car market in India accounts for nearly 3.4 million vehicles per year.
  6. LITERATURE REVIEW CARS24 Cars24 is a web platform where seller can sell their used car. It is an Indian Start-up with a simplified user interface which asks seller parameters like car model, kilometers traveled, year of registration and vehicle type (petrol, diesel). These allow the web model to run certain algorithms on given parameters and predict the price. GET VEHICLE PRICE Get Vehicle Price is an android app which works on similar parameters as of Cars24. This app predicts vehicle prices on various parameter like Fiscal power, horsepower, kilometers traveled. This app uses a machine learning approach to predict the price of a car, bike, electric vehicle and hybrid vehicle. This app can predict the price of any vehicle because of the smartly optimized algorithm.
  7. LITERATURE REVIEW CARTRADE CarTrade is web and Android platform where user can research New Cars in India by exploring Car Prices, Car Specs, Images, Mileage, Reviews, and Car Comparisons. On this app one can Sell Used Car to genuine buyers with ease. One can list their used car for sale along with the details like image, model, and year of purchase and kilometers so that it is displayed to lakhs of interested car buyers in their city. User can read user reviews and expert car reviews with images that help in finalizing a new car buying decision. CARWALE CarWale app is one of the top-rated car apps in India for new and used car research. It provides accurate on- road prices of cars, genuine user and expert reviews. It can also compare different cars with the car comparison tool. this app also helps you to connect with your nearest car dealers for the best offers available.
  8. TECHNOLOGY USED  SCIPY SciPy is a free and open-source Python library used for scientific computing and technical computing. SciPy contains modules for optimization, linear algebra, integration, interpolation, special functions, FFT, signal and image processing, ODE solvers and other tasks common in science and engineering.  Matplotlib Matplotlib is especially deployed for basic plotting. Bars, pies, lines, scatter plots and so on are part of visualization using matplotlib. Matplotlib is a graphics package well integrated with NumPy and Pandas. The MATLAB plotting commands are closely mirrored by the pyplot module
  9. TECHNOLOGY USED  Seaborn Seaborn provides various visualization patterns. It has easy and interesting default themes and uses fewer syntax. Statistics visualization is the speciality of seaborn and it is employed while summarizing data in visuals and additionally depict the data distribution.  Linear Regression Regression is a method for predicting a dependent component with the help of independent variables. The method is commonly used to predict and calculate correlations between independent and dependent variables. The regression model establishes a linear or exponential connection between independent and dependent variables.
  10. SYSTEM DESIGN A data flow diagram shows the way information flows through a process or system. It includes data inputs and outputs; data stores and the various sub processes the data moves through. DFDs are built using standardized symbols and notation to describe various entities and their relationships. In this project there is one DFD
  11. SYSTEM DESIGN True data is noisy. Therefore, it is necessary to clean data so that the actual information from the collected data can be acquired. Different processes are carried out to obtain the actual information such as manual encoding and one hot encoding. Then feature extraction is performed to extract necessary features. Linear regression modelling is used to train the dataset. User can give an input to the detection model and it will provide an output.
  12. Training Set Testing Set Literature Review Prediction Dataset Collection Data Pre-processing Feature Extraction Linear Regression Modelling Error Calculation
  13. EXPERIMENT AND RESULTS The dataset is imported and read for understanding car_data.head( ) car_data.isnull().sum()
  17. CONCLUSION In this project, a Linear Regression Model was successfully implemented employing various prominent algorithms from the python libraries and modules. After the collection of data was done, further processing of data was done. The null entries and missing datapoints were removed from the dataset and the categorical variables were also processed using One Hot Encoding technique. The r2 score of Linear Regression was 0.86 which is good and predictions were quite close to the original selling prices.
