Positional encoding is used to inject word order information into the model, because the attention mechanism itself does not distinguish positional order.

UnverifiedThe introduction of Positional Encoding compensates for the inherent lack of sequential order perception in the self-attention mechanism, because the attention computation itself is permutation-invariant.80% similarUnverifiedThe attention layer acts as an information router that aggregates context across different sequence positions, with its keys and values being short-term memory representations dynamically derived from other tokens in the prompt.77% similarUnverified自注意力机制的计算路径长度与序列长度无关,任意两个位置之间的信息传递都是直接的,解决了长序列建模中的梯度消失问题74% similarUnverifiedWhen text instructions precede image input, the Transformer's cross-attention mechanism causes the model to have already formed clear query vectors when encoding the image, preferentially activating visual regions semantically related to the target.72% similarUnverifiedThe "self" in the self-attention mechanism refers to tokens at different positions within the sequence attending to each other, not the model attending to its own parameters or state.72% similar
