Controllability Analysis of State Space-based Language Model

arXiv — cs.LGTuesday, November 25, 2025 at 5:00:00 AM
  • A recent study introduced the Influence Score, a controllability-based metric for analyzing state-space models (SSMs) like Mamba. This metric quantifies the impact of tokens on subsequent states and outputs, evaluated across various Mamba variants through multiple experiments. The findings reveal that the Influence Score correlates with model size and training data, indicating a deeper understanding of Mamba's internal dynamics compared to attention-based models.
  • The development of the Influence Score is significant as it enhances the understanding of Mamba's architecture, which is crucial for improving sequence modeling capabilities. By providing a quantitative measure of token influence, this research could lead to more effective applications of SSMs in natural language processing and other domains, potentially influencing future model designs and training methodologies.
  • This research aligns with ongoing efforts to improve the interpretability and efficiency of large language models (LLMs) and their applications in various fields. The exploration of Mamba's capabilities, alongside advancements in related frameworks and methodologies, highlights a broader trend towards enhancing model performance and understanding, particularly in complex tasks such as video processing and semantic detection.
