How Can Mamba Learn In Context with Outliers and Generalize Provably?

arXiv:2510.00399v2 Announce Type: replace Abstract: The Mamba model has gained significant attention for its computational advantages over Transformer-based models, while achieving comparable performance across a wide range of language tasks. Like Transformers, Mamba exhibits in-context learning (ICL) capabilities, i.e., making predictions for new tasks based on a prompt containing input-label pairs and a query, without requiring fine-tuning. Despite its empirical success, the theoretical understanding of Mamba remains limited, largely due to the nonlinearity introduced by its gating mechanism

Why this matters
Why now

The paper provides a theoretical understanding of Mamba's in-context learning capabilities, which is timely given Mamba's recent emergence as a computationally efficient alternative to Transformers.

Why it’s important

A deeper theoretical understanding of Mamba's ICL capabilities could accelerate its development and deployment, potentially leading to more efficient and powerful AI models for a variety of tasks.

What changes

The theoretical proof of Mamba's ability to learn in context, even with outliers, strengthens its position as a viable and potentially superior alternative to Transformer models in certain applications.
