Transition matrix. All gray pixels in this image correspond to entries in the matrix being zero. The colored pixels take on values \(\in \left[ {0,1} \right]\) which are here overlayed in %. The exact values stem from the mean of the learned parameters in "Application to oropharyngeal HNSCC" section. The exact shape of the grey “mask” depends on how one orders the states.
