The TUB Sign Language Corpus Collection

Eleftherios Avramidis, Vera Czehmann, Fabian Deckert +8

We present a collection of parallel corpora of 12 sign languages in video format, together with subtitles in the dominant spoken languages of the corresponding countries. The entir…

Dyslexify: A Mechanistic Defense Against Typographic Attacks in CLIP

Lorenz Hufe, Constantin Venhoff, Erblina Purelku +3

Typographic attacks exploit multi-modal systems by injecting text into images, leading to targeted misclassifications, malicious content generation and even Vision-Language Model j…

From What to How: Attributing CLIP's Latent Components Reveals Unexpected Semantic Reliance

Maximilian Dreyer, Lorenz Hufe, Jim Berend +3

Transformer-based CLIP models are widely used for text-image probing and feature extraction, making it relevant to understand the internal mechanisms behind their predictions. Whil…

Steering CLIP's vision transformer with sparse autoencoders

Sonia Joseph, Praneet Suresh, Ethan Goldfarb +6

While vision models are highly capable, their internal mechanisms remain poorly understood -- a challenge which sparse autoencoders (SAEs) have helped address in language, but whic…

Prisma: An Open Source Toolkit for Mechanistic Interpretability in Vision and Video

Sonia Joseph, Praneet Suresh, Lorenz Hufe +7

Robust tooling and publicly available pre-trained models have helped drive recent advances in mechanistic interpretability for language models. However, similar progress in vision…

SCAM: A Real-World Typographic Robustness Evaluation for Multimodal Foundation Models

Justus Westerhoff, Erblina Purelku, Jakob Hackstein +4

Typographic attacks exploit the interplay between text and visual content in multimodal foundation models, causing misclassifications when misleading text is embedded within images…
