So essentially,
AC Policy will help Multimodal LLMs perform better!
Paper: Law of Vision Representation in MLLMs (17 Pages)
Researchers from Stanford and UC Berkeley are interested in to understanding the key factors that make certain vision representations optimal for MLLMs by proposing the "Law of Vision Representation in MLLMs."
Hmm..What’s the background?
The researchers find a strong correlation between cross-modal alignment, correspondence in vision representation, and MLLM performance. This means that when a vision representation has high cross-modal alignment and accurate correspondence (AC), it leads to improved MLLM performance.
Ok, So what is proposed in the research paper?
The researchers define an AC score that measures cross-modal alignment and correspondence, demonstrating a linear relationship between the AC score and MLLM performance.
The paper also introduces the AC policy, which leverages the AC score to efficiently predict the optimal vision representation within a defined search space, reducing the need for expensive fine-tuning.
This approach allows for the exploration of a larger number of vision representations without significantly increasing computational costs.
What’s next?
The researchers remark that these could directions for future work:
Refining the Score for Enhanced Correspondence Measurement
Exploring Alternative Reference Models for Cross-Modal Alignment
Investigating Novel Vision Representations with High AC Scores
So essentially,
AC Policy will help Multimodal LLMs perform better!
