Project 2: Predicting House Prices

Problem Statement

After sailing through the seas of probability, hypothesis testing, and machine learning basics, you've arrived at the shores of your second project. This is where you get to apply what you've learned in a practical, real-world scenario. You've amassed a treasure trove of knowledge; now it's time to put that knowledge to work.  

In this second project, we will be exploring the fascinating challenge of predicting house prices. As you know, the housing market is a crucial part of any economy and has a direct impact on people's lives. Accurate price prediction can help both buyers and sellers make informed decisions, and this is an area where machine learning can play a significant role.

There are many factors that influence house prices, such as location, size, age, and condition. Additionally, there are both numerical and categorical features that need to be taken into account. For example, the number of bedrooms and bathrooms is a numerical feature, while the type of flooring or the color of the walls is a categorical feature. As you can imagine, dealing with such a diverse set of features can be challenging, but it's also what makes this project so exciting.

In this project, you will not only learn how to apply machine learning algorithms to a real-world problem, but you will also gain experience in data wrangling, feature engineering, and model evaluation. By the end of this project, you will have a comprehensive understanding of the house price prediction problem and the tools and techniques needed to solve it.

So, without further ado, let's dive right into our first section, the Problem Statement, to get a better understanding of what we're aiming to accomplish and how we will approach this exciting challenge.

The problem we're tackling here is simple to understand yet challenging to solve: How can we most accurately predict the selling price of a house based on a variety of features such as its size, location, number of bedrooms, etc.?

In formal terms, we're aiming to build a predictive model  f(X)  that maps features  X  to a house's selling price y. Mathematically, this can be represented as:


f(X) \rightarrow y

For the purpose of this project, we'll assume that you have access to a dataset that contains information about house sales, including various features  X  (e.g., square footage, number of bedrooms, neighborhood) and the actual selling price  y.

Example Code: Importing the Dataset

To get started, let's assume you're using Python and the pandas library to import your dataset.

# Importing the necessary libraries
import pandas as pd

# Loading the dataset
df = pd.read_csv('house_prices.csv')

# Display the first few rows of the DataFrame
df.head()

Download here the house_prices.csv file

When you run this code, you'll get a DataFrame that displays the first few records in your dataset. This will give you an initial idea of what kind of data you're working with.

Installing Necessary Libraries

# For data manipulation
pip install pandas numpy

# For data visualization
pip install matplotlib seaborn

# For machine learning
pip install scikit-learn

If you're new to Python or data science, you might not have these libraries installed. Don't worry; installing them is as easy as running the above commands in your command line or terminal. These libraries are crucial for data manipulation, visualization, and machine learning, and we'll be using them extensively throughout this project.
