Apply feature visualization to maximize a neuron's firing by using gradient-based optimization on the input.
Analyze dataset examples by examining the distribution of maximal activating images for a neuron from a dataset.
Identify interpretable neurons representing high-level concepts (e.g., objects, emotions, art styles).
Probe downstream effects of neuron activations to understand classification processes.
Note limitations: neuron-level analysis may not capture all complex encodings (e.g., geolocation).

What it does and when to use it

A checklist for interpreting neurons in AI models like CLIP. It involves using feature visualization and dataset examples to identify concepts represented by neurons and understand their role in classification.

Why it works

These methods provide concrete steps to systematically investigate what specific neurons within a model have learned to recognize, offering a window into the model's internal logic.
