Hi,
I’m regular follower of NH and I’m also interested in the 2nd leg of the mission, i.e the 2016+ KBOs encounters. Does anyone know when operations about this leg (starting with searching objects of interest with HST or some other earth-based means, I suppose) are expected to begin ? |

I'll bet that when you first start, they give you a bunch of pix that had likely KBO/Variables in them. That both lets you come up to speed and lets them get an idea of how good you are at it. Somewhere around 150 images, my find rate for KBOs dropped drastically. (I stopped at 300--my hand hurts.)
When I click the "My Icehuntings" link, I see that nearly everything I've marked has also been marked by 8 to 16 people, so I'll guess I'm on the right track. The rules I developed for myself are more or less as follows: 1) Don't click really little ones. 2) Don't click if it has even a single black pixel completely inside it. 3) Don't bother with asteroids unless they're very obvious. 4) Just skip bad pages--don't try to say why. (Did I mention my hand hurts?) :-) I think they ought to give us keyboard shortcuts for all the buttons; minimizing mouse movement really helps reduce RSI. --Greg |

Somewhere around 150 images, my find rate for KBOs dropped drastically. Like many, I find this a really exciting project. I'm interested in how it was set up, and your surmises suggest that we may not have been fully informed about what we would be 'fed' and what would be done with our responses. If true, that's unfortunate. Are there things we don't know about how our input is being used? This is a technique employed by psychologists but surely not necessary here. So, NH team (and I know you are our friends), is Greg right? |

If true, that's unfortunate. Why do you say that? It's a very sensible thing to do. When people are new to the task, it makes sense to give them plenty of well-understood images. I'd expect to have to discard the first few dozen from each person anyway. People are great at this sort of task, but a) they take time to master it and b] they benefit from a little help. Once someone is up to speed, then it makes sense to turn them loose on the less-well-understood stuff. But almost all human data labeling protocols I know of have an enrollment period. There's nothing wrong with that. --Greg |
