Insurance Charge MLOps Logs

Dataset Description

This dataset contains inference-time logs generated by a deployed machine learning model that predicts insurance charges based on customer attributes.

The data is produced by a Gradio application running on Hugging Face Spaces as part of an MLOps learning project.

Columns

  • age: Age of the individual
  • bmi: Body Mass Index
  • children: Number of dependents
  • sex: Gender (male, female)
  • smoker: Smoking status (yes, no)
  • region: Residential region
  • prediction: Predicted insurance charges (USD)

Data Generation

  • Model: Linear Regression (scikit-learn)
  • Inference type: Online inference
  • Logged per user interaction

Intended Use

This dataset is intended for:

  • Demonstrating inference logging
  • Monitoring model outputs
  • MLOps experimentation and learning

Limitations

  • Data is generated from user inputs and may not reflect real-world distributions
  • Logs may reset if the application is redeployed
