Encoder-Decoder

A neural network architecture with two parts: an encoder that processes the input into a representation, and a decoder that generates the output from that representation.

Definition

A neural network architecture with two parts: an encoder that processes the input into a representation, and a decoder that generates the output from that representation. T5 and BART are encoder-decoder transformers. Good for tasks where the output differs significantly from the input, like translation and summarization.
