Since Elo and PageRank can sometimes (but not always) be used in similar circumstances, is there a PageRank generalization that is similar to this approach for Elo?
- thanatropism 9y agoPageRank would weigh all games the same -- unless graph weights are somehow adjusted. Elo naturally weighs down older games. Put differently: PageRank models stable dominance relations, while Elo better reflects evolution in skill.
- carbocation 9y agoSuccinct and clear. Thanks!
- morelandjs 9y agoI'm going out on a limb here because I'm not familiar with page range, but yes you could use our margin-dependent Elo model to rank items. Classic Elo: A user visits a page and is shown a picture of two different types of Halloween candy. The user clicks the candy they like better. You run "win/loss" Elo on the candy matchups and rank the candies by their Elo rating. FiveThirtyEight did that here http://fivethirtyeight.com/features/the-ultimate-halloween-candy-power-ranking/ http://fivethirtyeight.com/features/the-ultimate-halloween-c... Margin-dependent Elo: A user visits a page and is shown a picture of two different types of Halloween candy. The user moves a sliding bar, say from -10 to 10, to indicate which candy they prefer. I can then run margin-dependent Elo rankings on those candy matchups and rank the candies by different moments of their Elo rating distributions.
