arXiv:2605.31245v1 Announce Type: new Abstract: Recently, sparse autoencoders (SAEs) have emerged as an attractive tool for interpreting and interacting with representations in practical neural networks. While it is common empirical folklore, we also show theoretically that SAEs are highly unstable: different training runs are likely to produce different concept dictionaries and sparse codes. We characterize the model properties that hinder the stability of real-world SAEs, and address each of these problems through minimal changes to the architecture and training procedure. Together, these ch
The rapid advancement and deployment of large language models have highlighted the urgent need for robust interpretability tools, making the stability of sparse autoencoders a critical research focus.
Improved stability and interpretability of sparse autoencoders are crucial for building more reliable, understandable, and manageable AI systems, thereby accelerating the development of advanced AI applications.
This research provides a pathway to more stable and interpretable SAEs, potentially leading to a deeper understanding of neural network representations and enabling more effective interaction with complex AI models.
