📰 ArXiv cs.AI
TAPS proposes a task-aware approach to improve speculative sampling in autoregressive generation
Action Steps
- Train a lightweight draft model on a task-specific corpus to improve proposal quality
- Use the trained draft model to propose future tokens for speculative decoding
- Verify the proposed tokens in parallel using a larger target model
- Fine-tune the draft model and target model jointly to optimize speculative decoding performance

Title: TAPS: Task Aware Proposal Distributions for Speculative Sampling
Abstract:
arXiv:2603.27027v1 Announce Type: cross Abstract: Speculative decoding accelerates autoregressive generation by letting a lightweight draft model propose future tokens that a larger target model then verifies in parallel. In practice, however, draft models are usually trained on broad generic corpora, which leaves it unclear how much speculative decoding quality depends on the draft training distribution. We study this question with lightweight HASS and EAGLE-2 drafters trained on MathInstruct,
