Transformers are SSMs: Generalized Models and Efficient Algorithms Through Structured State Space Duality

Summary

This research paper, published in May 2024 by researchers from CMU and Princeton, explores the relationship between Transformers and Structured State Space Models (SSMs), particularly in the context of Mamba2. The core contribution is likely the demonstration of a duality or equivalence between these two seemingly distinct architectures. This allows for the generalization of Transformer models, potentially leading to novel model designs and improved performance. The paper likely investigates how the structural properties inherent in SSMs can be leveraged to enhance Transformers. The mention of 'Efficient Algorithms' suggests the authors are focusing on computational advantages, probably including speed and memory efficiency. This work likely offers insights into the design of new, more efficient, and possibly more powerful models. The inclusion of 'Mamba2' in the keywords indicates a connection to and potential improvement over existing SSM architectures like Mamba.
