For example, in two dimensions, we have a point $[2,5]$, representing \mintinline{python}{bird_posts} and \mintinline{python}{bird_likes}. -In three dimensions, with three features including the bird id, we would have a matrix +In three dimensions, with three features including the bird id, we would have a vector \begin{equation} \begin{bmatrix} -0 & 0 & 12\\ -0& 2& 0 \\ -0& 0& 5 +12 & 2 & 5\\ \end{bmatrix} \end{equation} which tells us where that user falls on all three axes.
