WebNov 2, 2024 · Beam search has gained more and more in importance thanks to many new and improved seq2seq models. This PR moves the very difficult to understand beam search code into its own file and makes sure that the beam_search generate function is easier to understand this way. Additionally, all Python List operations are now replaced by … Constrained beam search gives us a flexible means to inject external knowledge and requirements into text generation. Previously, there was no easy way to tell the model to 1. include a list of sequences where 2. some of which are optional and some are not, such that 3. they're generated somewhere in the sequence … See more This blog post assumes that the reader is familiar with text generation methods using the different variants of beam search, as explained in the blog post: "How to generate text: using … See more Let's say we're trying to translate "How old are you?"to German.
