CLIP-Dissect: Automatic Description of Neuron Representations in Deep Vision Networks
share
In this paper, we propose CLIP-Dissect, a new technique to automatically describe the function of individual hidden neurons inside vision networks. CLIP-Dissect leverages recent advances in multimodal vision/language models to label internal neurons with open-ended concepts without the need for any labeled data or human examples, which are required for existing tools to succeed. We show that CLIP-Dissect provides more accurate descriptions than existing methods for neurons where the ground-truth is available as well as qualitatively good descriptions for hidden layer neurons. In addition, our method is very flexible: it is model agnostic, can easily handle new concepts and can be extended to take advantage of better multimodal models in the future. Finally CLIP-Dissect is computationally efficient and labels all neurons of a layer in a large vision model in tens of minutes.
