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 different decoding methods for language generation with Transformers" Unlike ordinary beam search, constrained beam search allows us to …
WebMar 21, 2024 · Greedy Search Decoder Greedy search decoding is a simple and commonly used algorithm for decoding in seq2seq models. In greedy search, at each decoding step, the decoder selects the token with the highest probability as the next token in the output sequence. This process is repeated until an end-of-sequence token is … WebJul 17, 2024 · Next, we can apply this to the output generated by the Greedy Search decoding method and calculate the log probability of the sequence generated. For this example, I will take a short synopsis ...
WebThe improved computational parallelism allows LLMA to achieve over 2x speed-up for LLMs with identical generation results as greedy decoding in many practical generation scenarios where significant overlap between in-context reference and outputs exists (e.g., search engines and multi-turn conversations). WebMar 21, 2024 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So the problems where choosing locally optimal also leads to global solution are the best fit for Greedy. For example consider the Fractional Knapsack Problem.
