k-Shape: Efficient and Accurate Clustering of Time Series

Summary: k-Shape introduces a scalable iterative refinement for time-series clustering using a normalized cross-correlation distance to emphasize shape. Robust centroid computation yields homogeneous, well-separated clusters, with experiments showing it outperforms scalable baselines and most non-scalable rivals in accuracy.
