Algorithm 4

Events_recognition function.

1Input: Aggregates

2Output: New_events

3create table New_events with columns time, event_type

4Times:= Select time from Aggregates

5for each t in Times do

6begin

7votes:= empty array

8for each classifier in ensemble

9begin

10[a, b]:= classifier_range

11data:= Select min_a_1, max_a_1,..., min_b_n, max_b_n

12from Aggregates where time = t

13event_type:= classifier(data)

14votes[event_type]:= votes[event_type] + classifier_weight

15end

16event_type:= arg max (votes[event_type])

17Insert t, event_type into New_events

18End
