💫 MemMamba: Rethinking Memory Patterns in State Space Model
💡Overview
The article tackles the escalating challenge of long‑sequence modeling in natural language processing and bioinformatics, where traditional recurrent neural networks (RNNs) falter due to gradient issues and transformers suffer quadratic complexity. By conducting rigorous mathematical derivations and an information‑theoretic analysis, the authors dissect the memory decay mechanism inherent in the state‑space model Mamba, revealing its exponential loss of long‑range context. To quantify this degradation, they introduce horizontal‑vertical memory fidelity metrics that capture intra‑layer and inter‑layer information loss. Dra ...
