Multidimensional temporal mining in clinical data
Shusaku Tsumoto, Shoji Hirano · 2012
Since medical and healthcare data include temporal trends of clinical symptoms, temporal data mining is one of the most important elements to discover knowledge. In this paper, we propose a three-dimensional trajectories mining method to capture the similarities between temporal trajectories of three selected variables. The method was evaluated on two datasets: one is on chronic hepatitis, and the other is on temporal trends of #orders in our university hospital. The results showed that, compared with conventional studies, the method gave more detailed classification of temporal trends.
