arXiv:2605.25619v1 Announce Type: new Abstract: In the paper we show that there is an analogy between the operations occurring in a layer of a transformer (projections and layer normalizations, disregarding the feedforward neural network) and a step in the power method. Coherently with this analogy, we show that passing through a layer the tokens tend to be tilted towards the principal eigenvector of a matrix which is the product of the output and value weight matrices of that layer. In the special case of a transformer with shared weights (i.e., in which all layers have identical weights) the
The continuous research into the fundamental mechanics of transformer models seeks to deepen understanding and improve their efficiency, a natural progression as AI models scale.
A deeper theoretical understanding of transformer operations can lead to more efficient architectures, better training methods, and potentially new capabilities, impacting the developmental trajectory of AI.
This research provides a new lens through which to view transformer layers, potentially informing future model designs that are more aligned with principal component analysis.
