Unverified主流LLM普遍存在U型注意力分布模式,对上下文开头和结尾信息处理效果最好,对中间部分较差70% similarVerifiedThe self-attention mechanism enables models to simultaneously handle long-range text dependencies, breaking through the sequential processing bottleneck of recurrent neural networks (RNNs).69% similarUnverified上下文图谱为智能体提供了介于临时上下文和模型权重微调之间的中间层记忆机制,可在不改变底层模型的前提下持续积累经验69% similarUnverifiedEach time a token is generated via a forward pass, the model must go through a complete multi-head attention computation and feed-forward network layers, with the amount of computation determined by the model's parameter scale68% similarUnverifiedThe VRAM occupied by the context window is calculated separately from the model weights, and KV cache VRAM usage grows linearly with context length.68% similar
