Separators in Enhancing Autoregressive Pretraining for Vision Mamba
This paper introduces STAR (SeparaTors for AutoRegressive pretraining), a novel method that significantly extends the input sequence length for Vision Mamba models by inserting unique separators before each image. This approach enables Vision Mamba to process multiple unrelated images as a single long-sequence task, quadrupling the effective input length and enhancing its ability to leverage long-range dependencies. The STAR-B model achieves 83.5% accuracy on ImageNet-1k, demonstrating improved performance over traditional short-sequence autoregressive pretraining by optimizing Mamba's inherent causal mechanism for extended contexts.

Effectiveness of Different Separator Types
An investigation into various separator types reveals their impact on representation learning effectiveness.
| Separator Type | FT (%) | EMA (%) |
|---|---|---|
| None | 78.64 | 78.63 |
| Token | 79.41 | 79.37 |
| Cluster | 82.15 | 82.40 |
| Zeros | 81.77 | 82.35 |
| Ones | 81.83 | 82.26 |
| Embeddings | 82.05 | 82.27 |
| Identity | 82.08 | 82.58 |
| Notes: Cluster-based and Identity separators show superior performance. | ||
Leveraging Mamba's Long-Sequence Prowess
Traditional autoregressive methods are constrained to short sequences. STAR overcomes this by enabling Vision Mamba to process quadrupled input sequence lengths, unlocking its full potential for handling extended dependencies across multiple images.
