The coordinate surfaces of the Cartesian coordinates (x, y, z). The z-axis is vertical and the x-axis is highlighted in green. Thus, the red plane shows the points with x = 1, the blue plane shows the points with z = 1, and the yellow plane shows the points with y = −1.

2019年9月23日 · To communicate the three spatial dimensions, we use the X,Y, Z coordinates. These denote height, width and depth. In referring to machinery we use the same X,Y, Z denotations, but we give them different values or meanings.

Cross product, the interactions between different dimensions (x*y,y*z, z*x, etc.) The dot product ($\vec{a} \cdot \vec{b}$) measures similarity because it only accumulates interactions in matching dimensions.

Basically $I(X,Y;Z)$ means the mutual information between $(X,Y)$ and $Z$ which can be written as follows: $$ I(X,Y;Z)=H(Z)-H(Z|XY). $$ The value tries to quantify intuitively the amount of information we know about $Z$ by knowing $X$ and $Y$.
