WebJul 26, 2024 · If you are resource-constrained and want to be fast, you use greedy search. If you can afford more processing and desire increased accuracy you use beam search. 3. Diverse beam search: The problem with beam search is that top N high probability paths are close to each other. That means only the last few words differ in the decoded output … WebNov 21, 2024 · I would like to use Huggingface Transformers to implement a chatbot. Currently, I have the code shown below.

Beam search can cope with this problem. At each timestep, it generates all possible tokens in the vocabulary list; then, it will choose top B candidates that have the most probability. Those B candidates will move to the next time step, and the process repeats. In the end, there will only be B candidates. chili recipes with ground beef and spaghetti
