The fewer features that are compared for each split the quicker the trees are built and the more random they are. Therefore the randomness parameter can be considered the number of features used when making splits. We evaluate accuracy given different randomness when using a K-means vocabulary in \ref{fig:kmeanrandom}. \begin{figure}[H] \begin{center} -- cgit v1.2.3-54-g00ecf
