arXiv:2606.00428v1 Announce Type: cross Abstract: Low-rank adapters are usually compared by sweeping a small set of ranks, but the rank also fixes the resolution of the parameter budget. For a $2048{\times}2048$ OPT attention projection, increasing LoRA by one rank stores $4096$ trainable scalars, leaving large gaps between feasible low-budget adapter sizes. This paper asks whether a tensorized adapter with finer capacity increments changes the observed accuracy--budget trade-off. We instantiate this question with fixed-component canonical polyadic (CP) tensor adapters. Under a $32{\times}64{\
The continuous drive for more efficient and robust large language models (LLMs) necessitates research into optimizing parameter-efficient fine-tuning (PEFT) methods, especially as model sizes grow.
Improving PEFT efficiency can significantly reduce the computational resources and memory required for adapting LLMs, making advanced AI more accessible and scalable across various applications.
This research suggests a more granular approach to PEFT capacity, potentially leading to more optimal trade-offs between model accuracy and computational budget compared to current methods like LoRA.

Tensorized adapters could offer finer control over parameter budgets in LLM fine-tuning.
This could lead to more energy-efficient AI model development and deployment.
Broader adoption of LLMs could accelerate due to lower operational costs and resource requirements.
