Segment Anything Model (SAM) with Prioritized Memory
Overview
The Segment Anything Model (SAM) by Meta is a state-of-the-art image segmentation model leveraging vision transformers. However, it suffers from high memory usage and computational inefficiencies. Our research introduces a prioritized memory mechanism to enhance SAM’s performance while optimizing resource consumption.
Methodology
We propose a structured memory hierarchy to efficiently manage image embeddings and self-attention transactions. Our approach consists of three key components:
Short-term Memory (M): Captures raw image patch embeddings and self-attention updates.
Intermediate Memory (P): Filters and refines the most significant embeddings dynamically.
Long-term Memory (SR): Stores only the most relevant embeddings to optimize efficiency.
This hierarchical approach reduces redundant computations, accelerates inference speed, and optimizes segmentation accuracy.
Findings
Our experiments demonstrate significant improvements in both efficiency and accuracy:
30.6% reduction in memory consumption.
40% increase in inference speed.
Improved segmentation accuracy compared to baseline SAM.
Usage
This research is intended for researchers and developers working on memory-efficient deep learning models, particularly in image segmentation and transformer-based architectures. Our approach can be extended to other vision tasks requiring optimized memory handling.
Future Work
Extending memory prioritization to 3D image segmentation.
Exploring adaptive memory selection using reinforcement learning.
