Left-to-right beam search decoder
NettetBart uses a standard seq2seq/machine translation architecture with a bidirectional encoder (like BERT) and a left-to-right decoder (like GPT). ... The method currently supports greedy decoding, beam-search decoding, sampling with temperature, sampling with top-k or nucleus sampling.

Nettet11. mar. 2024 · Beam search decoding is another popular way of decoding model predictions that leads to better results than the greedy search decoder in almost all cases. Unlike greedy decoder, it doesn’t just consider the most probable token at each prediction, it considers top-k tokens having higher probabilities (where k is called the beam-width … NettetLSTMs (with 380M parameters each) using a simple left-to-right beam-search decoder. This is by far the best result achieved by direct translation with large neural networks. For comparison, the BLEU score of a SMT baseline on this dataset is 33.30 [29]. The 34.81 BLEU score was
Nettet12. nov. 2024 · Attention-based encoder decoder network uses a left-to-right beam search algorithm in the inference step. The current beam search expands hypotheses and traverses the expanded hypotheses at the next time step. This traversal is implemented using a for-loop program in general, and it leads to speed down of the … Nettet22. mar. 2024 · Image from the Hugging Face post on traditional beam search. Unlike greedy search, beam search works by keeping a longer list of hypotheses. In the above picture, we have displayed three next possible tokens at each possible step in the generation. Here’s another way to look at the first step of the beam search for the …
Nettet11. mar. 2024 · Constrained Beam Search. Constrained beam search attempts to fulfill the constraints by injecting the desired tokens at every step of the generation. Let's say that we're trying to force the phrase "is fast" in the generated output. In the traditional beam search setting, we find the top k most probable next tokens at each branch and … Nettet2.2 Beam Search with Bidirectional Scoring (BidiS) A Beam search generates word by word from left to right: the token generated at time step tonly depending on past token, but would not affected by the future tokens. Inspired by the work of (Li et al.,2016a), we propose a Beam Search with Bidirectional Scoring (BidiS), which scores the B
The beam search strategy generates the translation word by word from left-to-right while keeping a fixed number (beam) of active candidates at each time step. By increasing the beam size, the translation performance can increase at the expense of significantly reducing the decoder speed.
