Don't GetKicked

dont't kicked
One of the biggest challenges of an auto dealership purchasing a used car at an auto auction is the risk of that vehicle might have serious issues that prevent if from being sold to customers.The auto community calls these unfortunate purchases 'kicks.

Kicked cars often result when there are tampered odometers, mechanical issues the dealer is not able to address, issues with getting the vehicle title from the seller or some other unforseen problem.Kick cars can be very costly to dealers after transportation cost, throw-away repair work and market losses in reselling the vehicle.

Modelers who can figure out which cars have a hihger risk of being kicked can provide real value to dealership trying to provide the best inventory selection possible to their customers.

What if i said, exploratory data analysis and machine learning can be used to provide the much needed insights on this vexing issue.

In this notebook, i will use several machine learning algorithms to predict which of the cars purchased during auction are bad buys.

The first step in achieving this, is to carry out an exploratory data analysis on the datasets which was gotten from Kaggle.Then, the features will be engineered to train and fine-tune machine learning classifier algorithms.

This project is part of the Machine Learning with Python:Zero to GBMs.

1. Download Don'tGetKicked Data

There are several ways one can get data. It can be from scraping of web using the beautifulSoup libraries or downloading the data directly from the source.For this project, my source of data is Kaggle which gives exclusive downloading right to only its members(those who registered with them). This makes it imperative for me to use the library OpenDataSets.This library by Jovian makes it a convenient downloading tools. It requires the user to input their Kaggle Username and API token to enable one to have access to the data.'')

2.Reading Of Data

In this section, i will the os module and pandas library to read the data.The os.Listdir() method is used to get the list of all files and directories in the specified directory downloaded fro Kaggle.For pandas, we will use pd.read_csv() which is used to read csv files.

import os
import opendatasets as od
import pandas as pd
pd.set_option('display.max_columns', 120)
pd.set_option('display.max_rows', 120)
import jovian
import numpy as np
