VerifiedThe Transformer's encoder is responsible for mapping the input sequence to a contextual representation and is suitable for classification and understanding tasks, while the decoder autoregressively generates the output sequence and is suitable for text generation tasks85% similarUnverifiedThe original Transformer paper used sinusoidal positional encoding, while subsequent models such as BERT switched to learnable positional embeddings.79% similarUnverifiedThe Transformer architecture generates text in an autoregressive manner, outputting one token at a time and appending it to the input sequence to predict the next token, resulting in a serial inference process78% similarUnverified大语言模型通常采用仅解码器（Decoder-only）的Transformer变体，通过因果掩码确保每个位置只能关注其之前的token78% similarUnverifiedTransformer inference is divided into two stages, prefill and decode: prefill processes the entire input prompt in parallel at once and is mainly compute-bound; decode generates output tokens one by one and is mainly memory-bandwidth-bound.76% similar
