Encoder-Decoder Architecture is a foundational concept in deep learning, particularly in the field of natural language processing (NLP). It serves as the backbone for various NLP tasks, including machine translation, text summarization, and question answering. Understanding Encoder-Decoder Architecture is crucial for anyone seeking to delve into the world of deep learning and NLP.
What is Encoder-Decoder Architecture?
Encoder-Decoder Architecture, as the name suggests, consists of two primary components: an encoder and a decoder. The encoder's role is to convert an input sequence, such as a sentence or a sequence of numbers, into a fixed-length vector. This vector captures the essential information and representation of the input sequence.
