BlackMamba: Mixture of Experts Approach for State-Space Models

The emergence of Large Language Models (LLMs) constructed from decoder-only transformer models has been instrumental in revolutionizing the field of Natural Language Processing (NLP) and advancing various deep learning applications, such as reinforcement learning, time-series analysis, and image processing. Despite their scalability and strong performance, LLMs based on decoder-only transformer models still face considerable limitations.

The attention mechanism in transformer-derived LLMs, while expressive, demands high computational resources for both inference and training, resulting in significant memory requirements for sequence length and quadratic Floating-Point Operations (FLOPs). This computational intensity constrains the context length of transformer models, making autoregressive generation tasks more expensive as the model scales and hinder their ability to learn from continuous data streams or process unlimited sequences efficiently.

Recent developments in State Space Models (SSMs) and Mixture of Expert (MoE) models have shown promising capabilities and performance, rivaling transformer-architecture models in large-scale modeling benchmarks while offering linear time complexity with respect to sequence length.
