Performance maps – a tool for examination of reliability of procedures for automatic separation of heterogeneous fault/slip and calcite twin data

The concept of performance maps is introduced in order to investigate a reliability of routines for automatic separation of polyphase fault/slip and calcite twin data. They show a performance of a given procedure in relation to a difference between superposed stress tensors and proportion between sizes of homogeneous subsets. The reliability of two procedures is investigated with performance maps – sequential separation for fault/slip data and s1 clustering for calcite twins. The results suggest a high reliability of the sequential separation and poor performance of σ1 clustering.
