This is a python-based example implementation of beam search, leveraging Hugging Face's transformers package to use a T5Tokenizer and T5-based Model.
This code and algorithm is discussed in detail in this blog post: Temperature Scaling and Beam Search Generation in LLMs, for the ML-Adjacent
Example usage:
$ python3 src/main.py --beam 4 --temperature 4.0 --input ./corpora/wiki-fox.txt --prompt "summarize the following document"
[ voluminous output ]
beam search (k=4, t=4.0) generation results:
