Beyond LoRA: Is Sparsity-Induced Adaptation Better?

Elijah Cadenhead, Cristian McGee, Xin Li +2

Low-rank adaptation (LoRA) and its variants provide a memory- and compute-efficient alternative to full fine-tuning of pre-trained models. However, questions remain about the compa…

Just Few States are Enough: Randomized Sparse Feedback for Stability of Dynamical Systems

Zaid Hadach, Hajar El Hammouti, El Houcine Bergou +1

While classical control theory assumes that the controller has access to measurements of the entire state (or output) at every time instant, this paper investigates a setting where…

Where Have All the Kaczmarz Iterates Gone?

El Houcine Bergou, Soumia Boucherouite, Aritra Dutta +2

The randomized Kaczmarz (RK) algorithm is one of the most computationally and memory-efficient iterative algorithms for solving large-scale linear systems. However, practical appli…
