The encoder builds source representations, and the decoder generates target elements conditioned on those representations.
Early seq2seq models used recurrent encoders and decoders. Bahdanau attention addressed the fixed-vector bottleneck by computing a source context for each decoder step. The Transformer replaces recurrence with self-attention and cross-attention. BART pretrains a denoising encoder-decoder, while T5 casts many language tasks as text-to-text. These papers evaluate specific models and tasks; the architecture alone does not guarantee quality.
A neural translation encoder represents a source sentence while a decoder generates a translated sentence.
Bahdanau attention lets each decoder step focus on different encoder states.
The Transformer uses encoder-decoder attention and masked decoder self-attention.
BART and T5 use encoder-decoder architectures for denoising or text-to-text tasks.
Choose an encoder-decoder when a task naturally maps one sequence to another, and compare it with alternatives on the target data and latency. Track input-length behavior and output quality. The cited work does not establish that this architecture is best for every language task.

Kisimbaji hutumia mfuatano mzima wa ingizo na hutoa vekta za muktadha zinazonasa maana yake, ambayo avkodare hutumia kisha.
Kufunika uso huhakikisha kila nafasi ya pato inashughulikia nafasi za awali pekee, kuhifadhi mpangilio wa kizazi cha urejeshaji kiotomatiki kutoka kushoto kwenda kulia.
Uangalifu mwingi huruhusu kila safu ya avkodare kuuliza hali fiche za kisimbaji, ikiunganisha uelewaji wa ingizo kwa uzalishaji wa matokeo.
T5 (na BART) ni miundo ya kawaida ya kusimbua ambayo hufanya kazi kama maandishi-kwa-maandishi. BERT ni encoder-tu na GPT-3 ni avkodare pekee.
Tafsiri huweka mlolongo mmoja hadi mwingine tofauti, kwa hivyo kusoma chanzo kizima (kisimbaji) na kutoa lengo jipya (kisimbaji) inafaa kikamilifu.
