Hi, I have two questions about the data challenge 2015.
1. In the test data sets, the first half of the fault file data is complete, while the second half is incomplete. I cannot understand this sentence well. How to distinguish the first half and second half? Also, some faults of type 1-5 are missing. Would you like to explain this sentence for me?

2. The sampling interval is roughly 15 minutes, however variations may occur due to logging delays. Do logging delays occur in all data sets? For example, if the logging time is 2009/8/18 18:30:00 (line 13 in plant_1a.csv), the actual logging time is 2009/8/18 18:15:00. Is my understanding right?

Thanks a lot & best regards.

1. The half boundary has not been provided yet, but will be provided for each of the test files and will be posted on the data site. “Missing” means some of the log lines representing faults are not provided.

2. Yes, logging delays may occur in all data sets. A logging delay should be strictly less than 15 minutes. So In your example, the logging time is 2009/8/18 18:30:00 (line 13 in plant_1a.csv) does not appear to include any delay. Consider the actual time to be logging time “modulo 15 minutes.”
