Diving into Kronecker Adapters: Component Design Matters

arXiv:2602.01267v2 Announce Type: replace Abstract: Kronecker adapters have emerged as a promising approach for fine-tuning large-scale models, enabling high-rank updates through tunable component structures. However, existing work largely treats the component structure as a fixed or heuristic design choice, leaving the dimensions and number of Kronecker components underexplored. In this paper, we identify component structure as a key factor governing the capacity of Kronecker adapters. We perform a fine-grained analysis of both the dimensions and number of Kronecker components. In particular,

Why this matters
Why now

The continuous drive for efficiency in large-scale AI model fine-tuning necessitates ongoing research into adapter architectures, with Kronecker adapters showing particular promise.

Why it’s important

Optimizing adapter design, specifically Kronecker adapters, can lead to more efficient and scalable training of large language models, impacting resource allocation and model performance.

What changes

The focus shifts from treating Kronecker component structure as a fixed choice to actively designing and exploring its dimensions and number for improved performance.
