it seems that most of the leading pictures in all categories I haven't seen!? They have these high scores but I don't get a vote in?? Others I have seen come up regularly are quite low scored in comparison.
How does this work?
The reason you don't see them in duels often is that there are very few of them so the probability of seeing one that you also saw on the leaderboard is very small. Keep in mind that at any given time on Pixoto there my be more than 30,000 images for the system to choose from.
We allocate duels to images that need more votes (there is a very complicated algorithm involved that determines this) so generally you're seeing newer images when voting.
The pictures have to start at the bottom before they can get to the top spots which means they should be in more frequent duels before they get there!? Still strange how I don't see them work their way up when it is nearly all the top shots I am talking about.
My pictures don't change score up or down, they just sit with the same number after only being on the site for 2 days. Most have won more than half of their duels. I still don't understand how this work
For more than 30,000 images, I do see the same one's repeated a lot.
Your comments and support are very much appreciated. I will keep trying. :)
Hope you all sort it out. I am going somewhere where it is fun!! Cheers.
Yesterday I submitted an image that climbed to 500 in almost no time and then the usual '500-break' arrives without possibility to get new votes. So what can you possibly do to give that image a boost so it can get higher -- maybe towards 700 ?
Another image got stuck shortly after submission and buying more votes did not help a lot.. I decided to resubmit and in no time it reached the 'break-point' of 500 and for the moment (one day later) it is at 545.
The score you get looks more and more like a lottery while the essential (the quailty of the image) remains unchanged...
ImageScore is generated from our proprietary algorithms and is meant to summarize how well the image has done against other images in its category and subcategory. Once an image has competed in sufficient duels, a higher score will naturally mean a higher perceived quality. ImageScore is recalculated at the end of every ImageDuel. Factors that determine how much ImageScore changes include the number of ImageDuels completed and the relative strength of the opponent.
Our goal is not to find the relative position of all images but instead to find the relative position of the BEST images. It is not important to us whether an image rates 50 or 51 out of 100. We really only want to put that image in the right area of the Leaderboard and will stop dueling (“pause”) images that are not statistically likely to reach the top 10%. By contrast it is important that we understand whether an image ranks number 3 or 4 out of 100 and will use a disproportionate number of ImageDuels to determine this.
Important Note: ImageScores are calculated only within categories and subcategories and cannot be compared across categories. For example a photo with an ImageScore of 650 in Wedding is NOT by definition better than an image with a score of 600 in Landscape & Nature.
We are the first to acknowledge that image quality is based on individual preference. It’s possible that you may hate an image that your friend loves. However, images that rise to the top of the Leaderboard are the ones that our users in aggregate like the most. In looking at the results of our ImageDuels we have found that people tend to vote fairly consistently when images are of obviously different quality levels. Images that are much closer in quality tend to have split opinions. So the “number one” image may be only a small fraction better than the “number two” image.
You should also note that images start at the bottom of the Leaderboard with an ImageScore of zero. Images must work their way up the Leaderboard based on their performance and this can take several days to stabilize.
How do you decide what images I see when I play ImageDuel?
Images are matched against other images based on a proprietary algorithm . Images with the least number of duels generally appear more often than those with larger numbers. If an image performs poorly in its first few duels its chance of being matched again drops significantly. By contrast images that are faring well in the duels will be displayed more often.
Win/Loss ratios are not a good indicator of ImageScore. We strive to keep the win/loss ratio as close to 50% as possible by pairing images with other images that we think might be close in quality (i.e. great images with great images, bad images against bad images, etc). While sometimes it is necessary to play images against images that are of vastly different quality, it is not our preferred method. To understand more about how ImageScores are calculated – read “What is an ImageScore” above.
Images get paused if they are statistically unlikely to move up to the top 10% of all images (approximately 615 ImageScore). Sometimes we determine this within this within 6 duels sometimes it takes 100. The key is that in order to provide good clarity into which images are in the top 10 we must vote the best images a lot. With a limited amount of duels available to us the best way to accomplish this is by pausing images once we’ve determined that they are not likely to get near the top. We use statistics so by definition we are not 100% confident that the image should be paused and so to address this issue we added the “get more votes” feature (the “play” button on the leaderboards). Under certain circumstances Paused images may still be placed in to duels and may be unpaused automatically.
