The paper "Vision Mamba: Efficient Visual Representation Learning with Bidirectional State Space Model" introduces a new generic vision backbone, Vim, which leverages bidirectional state space models (SSMs) to efficiently learn visual representations. Unlike traditional vision transformers (ViTs) that rely on self-attention, Vim uses position embeddings and bidirectional SSMs to capture global visual context and spatial information. This approach not only enhances the model's performance but also improves computational and memory efficiency, especially when dealing with high-resolution images. Key contributions of the paper include: 1. **Model Architecture**: Vim incorporates bidirectional SSMs and position embeddings to process image sequences, providing robust global visual context and location-aware recognition. 2. **Performance and Efficiency**: Vim outperforms established vision transformers like DeiT on tasks such as ImageNet classification, COCO object detection, and ADE20k semantic segmentation. It also demonstrates superior efficiency, achieving 2.8× faster inference and saving 86.8% GPU memory compared to DeiT when processing high-resolution images. 3. **Hardware-Aware Design**: The paper details hardware-aware optimizations to reduce IO-bound and memory-bound operations, making Vim suitable for modern hardware accelerators. Experiments on various datasets, including ImageNet, ADE20K, and COCO, show that Vim achieves higher accuracy and better efficiency compared to other state-of-the-art models. The paper also includes an ablation study to validate the effectiveness of the proposed bidirectional SSM and classification design. The authors conclude that Vim has great potential as a next-generation vision backbone, suitable for high-resolution images and long sequence modeling tasks. Future work will explore unsupervised tasks and multimodal applications using Vim.The paper "Vision Mamba: Efficient Visual Representation Learning with Bidirectional State Space Model" introduces a new generic vision backbone, Vim, which leverages bidirectional state space models (SSMs) to efficiently learn visual representations.
