Constrained Beam Search

Guiding Text Generation with Constrained Beam Search in 🤗 Transformers

This Hugging Face blog post introduces constrained beam search, a text generation technique that allows users to enforce hard constraints on model outputs, such as requiring specific tokens or phrases to appear in generated text. The method extends standard beam search by guiding the search process to satisfy user-defined constraints while still optimizing for fluency. The post covers the implementation available in the Hugging Face Transformers library, making the technique accessible to practitioners.
