| Input: the time interval threshold , distance threshold , atypical |
| dataset R |
| Output: The basic atypical cluster set basic_set |
| 1 repeat |
| 2 randomly select a seed record r from R; |
| 3 retrieve all the atypical connected records from r w.r.t. and ; |
| 4 group those records to form an atypical event E(S; T); |
| 5 initialize basic cluster; |
