New metric uses eigenvalues to analyze memory dynamics in sequence models

Researchers have introduced a novel metric using eigenvalues to analyze and compare the memory dynamics of different sequence modeling architectures, specifically softmax attention and State Space Models (SSMs). This approach, drawing from dynamical systems theory, allows for a unified analytical framework, revealing spectral signatures that correlate with task requirements and long-range dependency modeling. The findings suggest that eigenvalue analysis can inform architectural modifications, guide training processes, and provide insights into feature importance, ultimately aiming to improve the capabilities of sequence models.

    Eigenvalues as a Metric for Memory Dynamics in Sequence Models

    arXiv:2510.09379v2 Announce Type: replace Abstract: While softmax attention drives state-of-the-art performance in sequence modeling, its quadratic complexity motivates linear alternatives such as state space models (SSMs). Structural differences between the two model classes, ho…
