Unverified大语言模型通过注意力机制(Attention Mechanism)对上下文窗口内所有token同时计算相关性权重,而非像人类一样逐步阅读和筛选资料78% similarUnverifiedWhen processing text, the self-attention mechanism simultaneously sees all words in the entire sequence and dynamically calculates the correlation weight between each word and every other word, using parallel computation rather than processing word by word sequentially like early RNNs.74% similarUnverifiedEvery large language model has a maximum token limit it can process, and when the content accumulated by a long task approaches that limit the model will forget early content due to degradation of the attention mechanism over excessively long sequences.74% similarVerifiedThe memory of large language models fundamentally relies on the attention mechanism of the Transformer architecture, and its effective information capacity is limited by the number of tokens in the context window.73% similarUnverifiedAn agent typically contains a large language model as its brain, a number of callable tools as its hands and feet, as well as memory and workflow orchestration mechanisms.73% similar
