Lueur is a lightweight framework for Neuro Interpretability.

Lueur

Lueur (pronounced ly.œʁ) means "faint glow" in French. It is a minimal, modular toolbox for NeuroInterpretability.

Lueur is intended for researchers interested in understanding representations in artificial neural networks, particularly in contexts inspired by neuroscience. It collects a set of lightweight tools for attribution, feature visualization and concept extraction.

While deep networks are not biological systems, their internal structures often raise questions that intersect with those asked in cognitive science and neuroscience. As such models become more capable, it is increasingly important to study not only what they achieve, but how they structure information, and what kinds of functions they implicitly compute.

Lueur provides a small, hackable set of tools to aid in that investigation.

Scope

Lueur is built around PyTorch and provides tools for:

• Attribution methods (saliency, integrated gradients, smoothgrads, rise, ...)
• Feature visualization (fourier, maco, ...)
• Sparse dictionary learning (SAE variants for concept extraction)
• Visualization and analysis utilities
• Tutorials and reproducible interpretability workflows

Notebooks and Tutorials

The main companion notebooks and reports are hosted in the following repository: serre-lab/ExplainableNeuro

Installation

pip install lueur-torch
