Token-Efficient Change Detection in LLM APIs

Timothée Chauvin, Clément Lalanne, Erwan Le Merrer +3

Remote change detection in LLMs is a difficult problem. Existing methods are either too expensive for deployment at scale, or require initial white-box access to model weights or g…

Your Neighbors Know: Leveraging Local Neighborhoods for Backdoor Detection in Decentralized Learning

Sayan Biswas, Antoine Boutet, Davide Frey +7

Decentralized learning (DL) is an emerging machine learning paradigm where nodes collaboratively train models without a central server. However, the collaborative nature of DL make…

Log Probability Tracking of LLM APIs

Timothée Chauvin, Erwan Le Merrer, François Taïani +1

When using an LLM through an API provider, users expect the served model to remain consistent over time, a property crucial for the reliability of downstream applications and the r…

Mosaic Learning: A Framework for Decentralized Learning with Model Fragmentation

Sayan Biswas, Davide Frey, Romaric Gaudel +7

Decentralized learning (DL) enables collaborative machine learning (ML) without a central server, making it suitable for settings where training data cannot be centrally hosted. We…

Queries, Representation & Detection: The Next 100 Model Fingerprinting Schemes

Augustin Godinot, Erwan Le Merrer, Camilla Penzo +2

The deployment of machine learning models in operational contexts represents a significant investment for any organisation. Consequently, the risk of these models being misappropri…
