Cluster evolution analysis: Identification and detection of similar clusters and migration patterns

作者：

Highlights：

• A model for temporal cluster analysis that reflects behavior patterns over time.

• Detecting migration between clusters, appearance and disappearance of clusters.

• Two visual tools were developed to enable displaying entire data in a single graph.

• Model's functioning is illustrated in the complex situation of corporate bonds.
