Taste Trainer is a web app that allows users to rank images by taking image comparison tests. Users can compare their results with experts and improve their taste.
► frequently asked questions
What does my score measure?
Your Score measures how well you match the test creator's answers, and your Community Match compares with everyone who has taken the test. You can also compare your results with specific users.
What are lists?
Lists are created by admins to rank large image sets. They include domains such as Painting, Architecture, Sculpture, etc. Users don't need to complete the list in one session.
Can I filter images?
Users can filter which images to compare by creating a list set. Their comparisons count toward their overall list rankings regardless of which list set is active. To completely order the list, eventually all images must be compared.
► math questions
Do I have to compare every image with every other image?
No. The transitive property means that if A > B, and B > C, then A > C by definition. Therefore, we don't have to compare A and C because we already know the answer. This reduces the number of comparisons that are necessary for a complete rank.
Does the transitive property always work?
What if the best tennis player, for whatever reason, always loses to another tennis player. Maybe the not-so-good player figured out the good player's secret, or the not-so-good player has a specific playing style that is particularly effective against the good player. Whatever the reason, we are not measuring who would win in a head-to-head matchup, but rather, who is the better tennis player. And we can look at their rankings to determine that.
How can we compare apples to apples?
If an image comparison has two images that are not related, on what basis can we compare them? We should always base it on how they rank within their own domains. For example, if Michael Jordan is shown next to Tiger Woods, we can compare which is better at their own sport.
How many comparisons does it take?
The exact number depends on how the user answers the comparisons. The lowest possible number would be the total number of images in the list minus 1. For example, if there are 60 images in the list, it would take at least 59 comparisons to completely order it.
How is my score calculated?
The score is determined by how closely your results match with those being compared. The less similar they are, the lower the match score. It is more important to get the top half correct than the bottom half.
