Out with Transformers? Mamba’s Selective SSMs Make Their Case

Mamba’s selective SSMs excel in sequence modeling, outperforming LTI SSMs in synthetic tasks and competing with Transformers in NLP, DNA, and audio benchmarks. It maintains efficiency while demonstrating strong zero-shot evaluation results.
