I agree that there are many speed priors and that “a speed prior” is probably better than “the speed prior.” That being said, the dovetailing speed prior (which is what Schmidhuber is talking about) is usually what I imagine as the default speed prior (e.g. as in the starting point here).
I just remembered that we can tag users now; I’ll try tagging @evhub to check with his opinion.
