• Abstract: Interpretable computer vision models are able to explain their reasoning through comparing the distances between the image patch embeddings and prototypes within a latent space. However, many of these approaches introduce additional complexity, can require multiple training steps and often have a performance cost in comparison to black-box approaches. In this work, we introduce Component Features (ComFe), a novel interpretable-by-design image classification approach that is highly scalable and can obtain better accuracy and robustness in comparison to non-interpretable methods. Inspired by recent developments in computer vision foundation models, ComFe uses a transformer-decoder head and a hierarchical mixture-modelling approach with a foundation model backbone to obtain higher accuracy compared to previous interpretable models across a range of fine-grained vision benchmarks, without the need to individually tune hyper-parameters for each dataset. With only global image labels and no segmentation or part annotations, ComFe can identify consistent component features within an image and determine which of these features are informative in making a prediction.
