DynaMiCS: Fine-tuning LLMs with Performance Constraints using Dynamic Mixtures

Eleonora Gualdoni, Sonia Laguna, Louis Bethune +3

Multi-domain fine-tuning of large language models requires improving performance on target domains while preserving performance on constrained domains, such as general knowledge, i…

HyperTransport: Amortized Conditioning of T2I Generative Models

Valentino Maiorca, Eleonora Gualdoni, Xavier Suau +3

As foundation models grow in capability, the ability to efficiently and reliably control their behavior becomes critical. Fine-tuning these models can be costly, and while promptin…

What do your logits know? (The answer may surprise you!)

Masha Fedzechkina, Eleonora Gualdoni, Rita Ramos +1

Recent work has shown that probing model internals can reveal a wealth of information not apparent from the model generations. This poses the risk of unintentional or malicious inf…

LinEAS: End-to-end Learning of Activation Steering with a Distributional Loss

Pau Rodriguez, Michal Klein, Eleonora Gualdoni +5

The growing use of generative models in daily life calls for efficient mechanisms to control their generation, to e.g., produce safe content or provide users with tools to explore…

Scaling Laws for Forgetting during Finetuning with Pretraining Data Injection

Louis Bethune, David Grangier, Dan Busbridge +3

A widespread strategy to obtain a language model that performs well on a target domain is to finetune a pretrained model to perform unsupervised next-token prediction on data from…
