Architecture of Transformer Models Architecture of Transformer Models The transformer architecture functions as the core structural element which makes up Large Language Models. Through learning sequential data relationships the neural network detects context by monitoring word relationships in sentences as well as video and image data sequences. The transformer models enable fast and accurate text translation along with speech processing in near real-time. transformer The transformer architecture consists of the following fundamental components: User input along with embeddings serves as the model's starting point for processing. The embeddings process words into numerical representations which machine learning models understand.
Position encoding serves to transform word positions  within input sequences into numerical sequences for transformer model input. The encoder operates as a neural network that analyzes input text to produce hidden states which contain both meaning and contextual information.
The decoder uses the previous words  in the phrase to determine the following words in its output. The decoder receives an output sequence which has been right-shifted to enable it to use the preceding words.
The output sequence passes through the decoder to produce an output sequence based on the encoded input sequence. User input along with embeddings serves as the model's starting point for processing.
