Has anyone else seen this?

\n

I tried two similar appliances in different submissions to see which one was scored as right.  Now that I am sorting things out and have more confidence about the other appliances in those submissions, it looks like both appliances are scored as "On" in the backend solution even though the size of the signal fits one but not both.

\n

Oh, well ...

Hi Noam,

\n

 

\n

I think I know which appliances you're talking about. I wish I could have replied earlier, but you know, we were still competing against each other.

\n

I think you're talking about appliances 17 and 19 of House 1. One is GR PS4 and the other is GR LCD TV. If that is true, this is what I saw. It happens that most of the time both are turned on and turned off at the same time, so both score as on. 

\n

 

\n

In the private leaderboard, those two appliances are on in three intervals of 393, 188, and 77 minutes, which in total is 2*658 minutes, which makes a significant difference. Those ones may be some that you missed.

I am wondering if there is an easy way to figure out which appliances you found that I either missed or chose not to mark because I was not confident about them.

Luis, 

\n

It's funny that you mentioned that.

\n

You just answered two questions that I asked other threads in response to a question that I did not think was related to either.  

\n

In this thread I was actually referring to the two H1 vaccum cleaners (appliances 8 and 32).   Each vaccum cleaner is tagged only once in the tagged data and I believe these two tags were not well marked and are very confusing.  The only thing I could figure out from them was that both Vaccum cleaners had a very strong and somewhat similar HF signature that looked very different from other HF signatures.

\n

There are 4 instances where those HF signatures appear in the public fold and my submissions initially showed that in the back end, the "Portable Vaccum" (appliance 32)" was marked as on for at least three of these time periods.

\n

As time went on I was surprised to find out that the fourth occurrence which lasts only 2 minutes had both Vaccums marked as "On" in the backend solution and this is what I was referring to when I posted this thread.
