UnverifiedRegarding the encoding of absolute physical position, the community is divided: some argue for direct normalized input, while others believe relative position encoding or learnable position embeddings should be used, because absolute position may introduce unnecessary bias.75% similarUnverifiedPositional encoding is used to inject word order information into the model, because the attention mechanism itself does not distinguish positional order.72% similarUnverified在检测、分割、姿态估计等需要保留空间关系的任务中，等变性是不可或缺的，而分类任务中不变性可能足够68% similarUnverified该模型采用预测目标在画面中的像素点位置及机器人到达时的朝向，而非硬算实际空间距离66% similarUnverifiedAdditive sinusoidal positional encoding gives different attention scores for the same offset but different absolute positions, because after expanding the dot product, cross terms related to the absolute positions remain.66% similar
