Re: I am Wondering how 1 Person can get so many Goes at the SAME SN?

Yes, Blackprojects, this has been going on since day 1.....but fortunately not too often. I don't know the cause for sure but I think this happens when the classification system freezes up and the classifier has to close the session and log back on again to resume. ...

I know of at least two possible cause !!!

A) If one works with opening candidates in multiple tabs/windows (like right mouse click -> open in new tab/window) one can get multiple tabs/windows for the very same SN candidate. Now one must just log out and in again and one can get an additional entry in the discoverer list.

B) When one had logged out and comes back to check for new candidates and there are still candidates in the queue, one will will always get presented the top rated SN candidate. If one now logs in in a second tab/window, one can successfully classify the SN candidate in the first tab/window.

I'm guilty to have done both from time to time in three cases: A) When very obvious SNe were still not fully classified after 6h. B) When all the candidates were not finished up after 16-24 h. B) When an obvious SN did get very low ratings without any reason and was therefore one of the last couple of SN candidates in the queue.

Hello WR- glad to hear from you again. I did bitch about their decision on the science blog. I didn't anticipate a reply and indeed they never gave one.

A hint was put on the SN ZOO Site

that there mite be more for us tod but the Longer it takes for Some thing to come along the Harder it will be to get us

SN ZOOITES Interested!

Some will Probably Flatly refuse to get involved

Others will Think about it Long and hard

Others will Try it not Like it and Walk away

a Few will Jump in Click and se what happens.

I am Undecided which way i will Go


The Longer it takes the Number of us Will Deminsih till None of us are Left or Interested!

So  Super Nova  Zooites would have seen the M82 SN but the PTF Computer said it was not a Supernova Hehehe  !

Joey and Mark have made a very bold claim indeed. The HZ’s do retain a complete image data collection for the whole periods 2010 through 2012. Several posts on the supernovae threads noted supernovae discoveries despite bad and chronic data imagery. distortion etc. Yet with our names, generally 10-20 participants, were appended to manyof those discoveries despite considerable consternation on our part. The ML claim appears to imply that even bad data can be transformed into enhancing discovery rates This is patently absurd. There was ample time to provide feedback during the last three years but participation by the machines was was even more minimal than Clarke and Pohl’s Machine Stored in the “Last Theorem”, and consider what their demise was.

I hope the PTF team are eating humble pie. http://blog.galaxyzoo.org/2012/08/03/machine-learning-supernovae/#comments

The bottom line is that after a further year of machine learning, and I certainly don't blame their computers, the M82 SN image was so obvious we could have trained monkeys to spot it! Please pass the message on to them.
