I have a theory (after having searched for The Diamond Age) that certain very popular books are ironically not going to be close to similar books because they appear on so many varied reading lists.
There's probably a graph theory phenomena that describes what I'm thinking.
- twosdai 3y agoYeah basically what I think you're saying is that in a weighted graph, if there are edge weights which are orders of magnitude larger then the average it throws off certain models. Like nearest neighbor. Basically just prune the top and bottom %1 of weighted edges to get an appropriate average. Would be my guess for a fix.
- bwb 3y agoYep this is 100% true (i run shepherd.com). Within our data books like lord of the rings and harry potter are nearly impossible to map for "books like" because they are connected to so many other things. I am working now to fine tune our model, but it has been an interesting challenge.
