This Jupyter Notebook provides a step-by-step guide to using SHAP (SHapley Additive exPlanations) values to interpret predictions made by a Random Forest model for credit fraud categorisation. Additionally, it leverages ChatGPT to provide natural language explanations for the model's predictions.
Setup Instructions:
Make sure you have the necessary Python packages installed.
Obtain an API key from OpenAI GPT-3 by following the instructions on the OpenAI website.
Set your OpenAI API key as a variable.
Run the Jupyter Notebook: Open the Credit_Fraud_SHAP_Explanation.ipynb notebook in Jupyter and execute each cell step by step.
Understand how the SHAP values contribute to the predictions made by the Random Forest model. Visualizations and explanations are provided to interpret the impact of each feature on individual predictions.
Utilize ChatGPT to generate natural language explanations for the model's predictions. The notebook demonstrates how to integrate ChatGPT using the OpenAI GPT-3 API for more human-friendly and interpretable explanations.
Feel free to adapt the notebook for your specific use case or dataset. Update the model, features, or integrate additional steps as needed.
