# example_dataset.csv
# This CSV file provides a sample dataset for demonstrating feature engineering techniques within the feature-engineering-toolkit plugin.
#
# Column Descriptions:
#   - user_id: Unique identifier for each user (integer).
#   - age: Age of the user (integer).
#   - gender: Gender of the user (categorical: Male, Female, Other).
#   - signup_date: Date the user signed up (YYYY-MM-DD).
#   - last_login: Date of the user's last login (YYYY-MM-DD).
#   - total_purchases: Total number of purchases made by the user (integer).
#   - avg_purchase_value: Average value of each purchase (float).
#   - country: Country of the user (categorical).
#   - marketing_channel: The marketing channel through which the user signed up (categorical).
#   - is_active: Indicates whether the user is currently active (boolean: True, False).
#   - churned: Target variable indicating whether the user churned (boolean: True, False).  This is what we want to predict.
#
# Instructions:
#   - Use this dataset to experiment with feature engineering techniques.
#   - Consider creating new features such as:
#     - Time since signup (calculated from signup_date).
#     - Time since last login (calculated from last_login).
#     - Purchase frequency (total_purchases / time since signup).
#     - Age groups (binning the age variable).
#     - Interactions between features (e.g., age * avg_purchase_value).
#   - Use feature selection techniques to identify the most important features for predicting churn.
#   - Apply feature transformations (e.g., scaling, normalization, encoding categorical variables).
#   - Remember to handle missing values appropriately (if any).
#   - The 'churned' column is the target variable.  The goal is to build a model that accurately predicts churn.
