MambaMia-Vicuna-7B-Mini

This is the MambaMia Mini model based on lmsys/vicuna-7b-v1.5, designed for efficient long-form video understanding.

Model Description

MambaMia is a State-Space-Model-based hierarchical compression method for efficient video understanding in Large Multimodal Models (LMMs). It addresses the computational cost and information redundancy challenges in processing long videos.

Key Features:

• Hierarchical compression using State-Space Models (SSM)
• Gated attention mechanism
• Learnable sampling strategy
• Significantly reduced memory usage and faster inference compared to existing LMMs

Usage

Please refer to the MambaMia repository for detailed usage instructions.
