About
State Space Models (SSMs) offer an intriguing alternative to the ubiquitous Transformer architecture in generative AI and large language models (LLMs). Their roots in control theory and signal processing lend a unique perspective to deep learning, particularly for modeling sequences. Initially conceptualized to manage exceptionally lengthy sequences, SSMs were revitalized by the pioneering efforts of Voelker, Kajic, and Eliasmith in 2019. Their work drew from neuroscience, showcasing the potential of SSMs to efficiently synthesize temporal information. This laid the groundwork for subsequent innovations in SSM-based architectures.
