LMEye: An Interactive Perception Network for Large Language Models
share
Training a Large Visual Language Model (LVLM) from scratch, like GPT-4, is resource-intensive. Our paper proposes an alternative method called LMEye, a play-plug-in Interactive Perception Network for Large Language Models (LLMs), aiming to improve the accuracy of image understanding for the LVLM. Previous methods that infuse visual information into LLMs utilize a static visual mapping network, but lack dynamic interaction between the LLMs and visual information. LMEye addresses this issue by allowing the LLM to incorporate the visual information that aligned with human instruction. Specifically, the LMEye network consists of a static visual mapping network to provide the basic perception of an image to LLMs. Then, it also contains additional linear layers responsible for acquiring requests from LLMs, decomposing image features, and transmitting the interleaved information to LLMs, respectively. In this way, LLMs act to be in charge of understanding human instructions, sending it to the interactive perception network, and generating the response based on the interleaved multimodal information. We evaluate LMEye through extensive experiments on multimodal question answering and reasoning tasks, demonstrating that it significantly improves the zero-shot performance of LLMs on multimodal tasks compared to previous methods.
