Measuring and Steering LLM Computation with Multiple Token Divergence
Analysis
This paper introduces a novel method, Multiple Token Divergence (MTD), to measure and control the computational effort of language models during in-context learning. It addresses the limitations of existing methods by providing a non-invasive and stable metric. The proposed Divergence Steering method offers a way to influence the complexity of generated text. The paper's significance lies in its potential to improve the understanding and control of LLM behavior, particularly in complex reasoning tasks.
