Commit Locally, Exit Globally: Coordinating Adaptive Sampling and Early Exit in Diffusion Language Models
TL;DR
C4 is a novel framework that enhances diffusion language models by coordinating adaptive sampling and early exit strategies, achieving significant speedups in decoding. It reduces decoding steps by 64-95% while improving end-to-end processing speed by 2.6 to 8.6 times.
✦ Why It Matters
Implement C4 in your diffusion language models to significantly enhance decoding efficiency and speed.
Key Takeaways
- Adopt the C4 framework for improved language model efficiency.
- Utilize CVEE for confident early exits in predictions.
- Implement CCTC to optimize token commitment during decoding.
- Test C4 on various tasks to evaluate performance gains.
How It Works
C4 coordinates two mechanisms: CVEE assesses when to stop generating based on confidence and stability of predictions, while CCTC determines which tokens can be committed during each step. This allows for local acceleration of predictions without affecting the overall sequence termination.
