CBR-FoX: Case-Based Reasoning for Time Series Prediction Explanations

CBR-FoX is a Python library designed to provide case-based reasoning explanations for time series prediction models. This approach enhances the transparency and interpretability of machine learning models applied to sequential data.

Features

• Case-Based Reasoning (CBR) Implementation: Utilizes case-based reasoning to enhance explainability in time series predictions.
• Versatile & Adaptable: Supports various types of time series data.
• ML Model Compatibility: Easily integrates with common machine learning models.
• Comprehensible Explanations: Provides clear, human-readable insights into model predictions.

Installation

To install CBR-FoX and its dependencies, follow these steps:

Install via GitHub

# Clone the repository
git clone https://github.com/jerryperezperez/CBR-FoX.git
cd CBR-FoX

# Install required dependencies
pip install -r requirements.txt

Usage

Follow these steps to use CBR-FoX in your projects:

1. Retrieve Model Information

Extract the relevant inputs and outputs from your AI model.

2. Create CBR-FoX Instances

from cbr_fox import CBRfoxInstances
cbr_instances = CBRfoxInstances(model_outputs)

3. Initialize the Builder

from cbr_fox import CBRfoxBuilder
builder = CBRfoxBuilder(cbr_instances)

4. Train the Instance

builder.fit(train_windows, train_targets, target_to_analyze, window_to_predict)

5. Obtain Explanations

builder.predict(prediction=prediction, num_cases=5)

6. Visualize Results

builder.visualize_pyplot(
    fmt='--d',
    scatter_params={'s': 50},
    xtick_rotation=50,
    title='Example Visualization',
    xlabel='X-axis',
    ylabel='Y-axis'
)
