VerifiedBefore the advent of Transformer, the field of natural language processing relied primarily on RNNs and LSTMs to process sequential data, architectures that had to process text word by word in sequence and could not perform parallel computation75% similarUnverifiedThe Transformer architecture underlying large language models does not directly process raw characters; instead, it first uses a tokenizer to split text into subword units, which are then mapped to high-dimensional vectors for computation.75% similarUnverifiedTransformer模型只能处理数值张量，需要分词器将文本转换为整数ID序列后通过嵌入层映射为连续向量71% similarUnverifiedThe core function of the Transformer is to take a text sequence as input and output a function for the next word70% similarUnverifiedThe 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 tasks68% similar
