This would be pretty... ugh... difficult to say the least. I agree though, it would be pretty interesting (and awesome). We would basically need to have most features of the environment we are trying to map through and update them regularly.
- gamegoblin 12y agoI'm imagining some sort of giant feature-based hash table. What does "three oak trees, a light post, and a mailbox in relative positions [data vector]" hash to? That's an interesting problem. It also has to be some sort of nearest neighbor hash where the same hash without the mailbox component (or with additional preciously untagged components) allowed you to find the same stuff. So I guess this is starting to sound like sparse KNN.
