A Distance-Based Clustering Framework for Categorical Time Series: A Case Study in Episodes of Care Healthcare Delivery System
… initialization strategies as well as cluster validation indices, though it focusses on the use of the Prediction Strength (PS) to address the concept of reproducibility in clustering. Since the recovery of the unknown true number of clusters true k is important, a simulation study is performed …

Acoustic data optimisation for seabed mapping with visual and computational data mining
… validated using four different internal validation methods. Next we tested two novel approaches in singlebeam echosounder (SBES) data processing and clustering – using visual exploration for outlier detection and direct clustering of time series echo returns. Visual exploration identified …
