WebThe default decoding strategy is greedy search, which is the simplest decoding strategy that picks a token with the highest probability as the next token. For many tasks and small output sizes this works well. However, when used to generate longer outputs, greedy search can start producing highly repetitive results.

WebThis is a very common problem in language generation in general and seems to be even more so in greedy and beam search - check out Vijayakumar et al., 2016 and Shao et al., 2024. The major drawback of greedy search though is that it misses high probability words hidden behind a low probability word as can be seen in our sketch above: WebJul 9, 2024 · Figure 2: Beam Search with BeamWidth=2 . 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.
