What is MVoT?
MVoT (Multimodal Visualization-of-Thought) is a novel multimodal reasoning paradigm developed by Microsoft Research, the Language Technologies Lab at the University of Cambridge, and the Institute of Automation, Chinese Academy of Sciences. It enhances the performance of Multimodal Large Language Models (MLLMs) in complex spatial reasoning tasks by generating visual reasoning traces. MVoT mimics the human mechanism of simultaneously using language and images during thinking, allowing the model to generate interwoven reasoning traces of text and images during the reasoning process, thus more intuitively expressing the reasoning process. MVoT addresses the inconsistency between the language and visual embedding spaces in autoregressive MLLMs by introducing token discrepancy loss, significantly improving the quality of generated images and the accuracy of reasoning.
Main functions of MVoT
- Generate visual reasoning tracesGenerates the reasoning process in the form of images, helping the model better understand and express the logic and changes in spatial reasoning tasks.
- Improve reasoning accuracyBased on visual reasoning traces, it can more accurately capture spatial layout and visual patterns, thereby improving the model's performance in complex spatial reasoning tasks.
- Enhancing model interpretabilityThe visual reasoning traces generated by MVoT provide an intuitive explanation of the model's reasoning process, allowing users to more clearly understand how the model arrives at its conclusions.
- Improve reasoning robustnessIn complex environments, MVoT exhibits better stability and adaptability, and handles environmental complexity and dynamic changes more effectively.
MVoT Technical Principles
- Multimodal reasoning paradigmBased on the visualization of reasoning traces generated from images, the model uses [this information] during the reasoning process.It employs both language and image modalities. This paradigm is similar to the mechanism by which humans use both language and images simultaneously when thinking, allowing for a more natural expression of complex reasoning processes.
- Token Discrepancy LossTo address the inconsistency between language and visual embedding spaces in autoregressive MLLMs, a token discrepancy loss is introduced. This loss improves the quality and visual coherence of generated images by minimizing the difference between predictions and labels in the visual embedding space.
- Intertwined reasoning tracesThe model generates interwoven text and image reasoning traces during the reasoning process. Each reasoning step includes a textual description and a corresponding image visualization, allowing the model to more comprehensively express the reasoning process.
- Training strategyThis approach trains the model on multimodal inputs and corresponding output labels, enabling it to generate interleaved reasoning traces. Training data includes multimodal inputs, language and image sequences during the reasoning process, and the final answer. This allows the model to better understand and generate multimodal reasoning processes.
- Recursive generationDuring the reasoning process, multimodal reasoning traces are recursively generated, and reasoning continues based on the images and text generated in the previous step. This recursive generation method more naturally simulates the human reasoning process and avoids potential errors introduced into image descriptions.
