New ASAp algorithm improves grammar-aligned decoding for LLMs

Researchers have developed a new decoding algorithm called Adaptive Sampling with Approximate Expected Futures (ASAp) to address limitations in grammar-constrained decoding for large language models (LLMs). Existing methods can distort the LLM's output distribution, leading to lower quality results even when grammatically correct. ASAp aims to ensure outputs are both grammatical and align with the LLM's original probability distribution, as demonstrated by its performance on code generation and structured NLP tasks. AI

IMPACT Improves the reliability and quality of structured output generation from LLMs, crucial for tasks like code and markup generation.

    Grammar-Aligned Decoding

    arXiv:2405.21047v4 Announce Type: replace Abstract: Large Language Models (LLMs) struggle with reliably generating highly structured outputs, such as program code, mathematical formulas, or well-formed markup. Constrained decoding approaches mitigate this problem by greedily rest…
