Transformer consists of the encoder, decoder and a final linear layer. The output of the decoder is the input to the linear layer and its output is returned.

Dec 03, 2019 · Thanks to transformers being central in the ecosystem and making state-of-the-art models available, encoder-decoder models benefit from a substantial compounding effect: 11 models implemented in...

Like earlier seq2seq models, the original Transformer model used an encoder-decoder architecture. The encoder consists of encoding layers that process the input iteratively one layer after another, while the decoder consists of decoding layers that do the same thing to the encoder's output.

If there are only pytorch checkpoints for a particular encoder-decoder model, a workaround is ... from transformers import BertConfig, EncoderDecoderConfig, ...

Jan 04, 2019 · Like LSTM, Transformer is an architecture for transforming one sequence into another one with the help of two parts (Encoder and Decoder), but it differs from the previously described/existing...

TransformerEncoder class torch.nn.TransformerEncoder(encoder_layer, num_layers, norm=None) [source] TransformerEncoder is a stack of N encoder layers Parameters encoder_layer – an instance of the TransformerEncoderLayer () class (required). num_layers – the number of sub-encoder-layers in the encoder (required).

The augmented embedding vectors are fed into the encoder block, consisting of the two sublayers explained above. Since the encoder attends to all words in the input sequence, irrespective if they precede or succeed the word under consideration, then the Transformer encoder is bidirectional.
