A pointer network is a class of attention-based sequence-to-sequence model that directly points to elements in the input as outputs via attention weights, so the output space changes dynamically with the input size.

UnverifiedWhen a large language model processes input, it computes Key and Value vectors in the attention mechanism for each token, and these vectors are reused repeatedly when generating replies.73% similarUnverifiedThe context window refers to the total number of tokens a model can see in a single inference, including input and output; the computational cost of the attention mechanism grows quadratically with sequence length.72% similarVerifiedThe self-attention mechanism allows the model to dynamically compute relevance weights between each element in a sequence and all other elements, capturing long-range dependencies.70% similarUnverifiedIn the attention mechanism of current large models, the query vector is indirectly shaped by the task context and objective function, making it closer to the top-down mode.70% similarUnverified思维链将模型内部工作记忆外部化，把中间推导结果存入上下文，借助注意力机制随时读取和复用70% similar
