v. meant (mĕnt), mean·ing, means v.tr. 1. a. To be used to convey; denote: "'The question is,' said Alice, 'whether you can make words mean so many different things'" (Lewis Carroll). b. To act as a symbol of; signify or represent: In this poem, the budding flower...
The meaning of VECTOR is a quantity that has magnitude and direction and that is commonly represented by a directed line segment whose length represents the magnitude and whose orientation in space represents the direction; broadly : an element of a vect
Normalizinga vector means reducing its length to1while preserving its direction. 很明显,这里的归一化应该叫做Scaling to unit length,缩放到单位长度1。那么为什么移动的时候需要这样处理呢?咱们先从移动控制说起。 移动控制 我们知道,Godot在使用键盘作为输入时,它只有两个值:0和1。按下按键即为1,不按则为0...

Next, since the produced vector meson \rho ^0 will decay into \pi ^+\pi ^-, its contributions to the \pi ^+\pi ^- invariant mass distributions in the B^{0}_{s} decay can be obtained by means of the spectral function [46, 81, 82], \begin{aligned}&\frac{d \varGamma _{B^...
RQ相比naive的kmeans量化误差更小,理论上也效果更好 随着生成topk的增加,耗时也会相应增加,和目前的方法相比效率上不占优,需要一些网络infer加速的方法 My 2 cents: 效果主要取决于原始embedding样本空间和docid生成方式。 pros: 可以用sequence2sequence建模复杂的非线性操作,弥补embedding本身的一些缺陷 ...
