House Price Prediction

Predicting house prices using machine learning models.

Overview

The primary goal is to build and evaluate various models to predict house prices based on the housing price dataset.

The models used include:

• Linear Regression
• Lasso (L1)
• Ridge (L2)
• Random Forest Regression

Dataset

The dataset used is sourced from Kaggle and includes various features related to house prices.

Workflow

1. Reading the Data:

   • Load and inspect the dataset.
   • The raw data is located in the data directory under the name housing.csv.

2. Exploratory Data Analysis (EDA):

   • Explore the data size.
   • Explore the data types and check for empty values.
   • Analyze the data by visualizing its features.
   • Analyze the correlation between the features.

3. Data Preprocessing:

   • Convert lat & long coordinates to city using the LocationIQ API.
   • Replace Unknown city values with the nearest city using NearestNeighbors, based on lat & long coordinates.
   • Remove unnecessary features.
   • Detect and handle outliers using IQR & KNN.
   • Encode categorical features using One-Hot Encoding.
   • Split the dataset into inputs & outputs, then split it into train & test sets.
   • Ensure the data is ready for training and evaluation.

4. Model Training & Evaluation:

   • Train multiple models using a Pipeline:
     • Linear Regression
     • Lasso (L1)
     • Ridge (L2)
     • Random Forest Regressor
   • Evaluate the performance of each model using the RMSE loss function and R² score.
   • Compare predicted values with actual values.

5. Save & Load the Models:

   • Save the models to .pkl files inside the models directory.
   • Load the models and make predictions.

Dependencies

• pandas: Data manipulation and analysis.
• numpy: Numerical operations on arrays.
• scikit-learn: Machine learning algorithms and tools.
• matplotlib: Plotting and visualization.
• seaborn: Data visualization.
• requests: Sending HTTP requests (used for LocationIQ API).

To start using this project, follow the steps below:

1. Clone this repository to your local machine:

   git clone [email protected]:IsmaelMousa/house-price-prediction.git

2. Navigate to the house-price-prediction directory:

   cd house-price-prediction

3. Set up a virtual environment:

   python3 -m venv .venv

4. Activate the virtual environment:

   source .venv/bin/activate

5. Install the required dependencies:

   pip install -r requirements.txt

   jupyter-notebook

Important

For reverse geocoding, the LocationIQ API is used. If you wish to perform reverse geocoding, sign up here and replace the placeholder with your token:

key = "YOUR_LOCATIONIQ_API_KEY"

If you don't want to try the reverse geocoding, you can skip this step.

Results

The results include performance metrics for each model and comparisons of predicted versus actual values.

Detailed analysis and model performance summaries are provided in the main.ipynb.
