UnverifiedCurrent mainstream large language models generally adopt the Transformer architecture, whose self-attention mechanism has a computational complexity that grows quadratically with sequence length (O(n²)) when processing long contexts.75% similarVerified基于Transformer的大语言模型使用注意力机制将系统提示、用户输入和外部检索内容统一编码为同质化的token序列，模型无法在语义层面区分可信指令与不可信数据75% similarUnverifiedTransformer uses Positional Encoding to retain word order information while performing parallel computation.74% similarVerifiedLarge language models are based on the Transformer architecture and are trained on massive amounts of text data.73% 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.73% similar
