Fromm: on behalf of Ben Goertzel To: Jeffrey Epstein <jeevacation®gmail.com> Subject: Re: Date: Mon, 12 Oct 2009 13:02:28 +0000 As a general rule, Hawkins thinks the only good work is done by Hawkins and his employees .... I.e., he is extremely sure he has the One True Path ... far more so than all the rest of us egomaniacs.... I doubt that Poggio knows about Itamar's work, but I suspect he would like it. Regarding perception processing, Itamar has the same basic philosophy as Poggio ... the difference is that Poggio is focusing on brain modeling whereas Itamar is trying to build AGI. Which allows Itamar to insert architectural features (like extensive feedback connections) whose biological details aren't yet known. At the Industry Day for the DARPA Deep Learning BAA (a few months ago), Itamar and I talked to the guys who are working on commercializing Poggio's stuff for image and video classification, and they said they are having a lot of trouble getting good results on practical problems. But Poggio himself wasn't there... Getting together with Poggio and Itamar and you for a chat on vision and AGI would be good fun. I talked to Poggio briefly after a talk he gave at Princeton a couple years ago, but don't really know him well (and he may not remember me)... ben On Mon, Oct 12, 2009 at 8:46 AM, Jeffrey Epstein <[email protected]> wrote: > what does poggio tand hawkins think of itamrs work„ i;d be interested to > know > On Mon, Oct 12, 2009 at 8:15 AM, Ben Goertzel <-> wrote: >> >> Hi, >> >> Yes, that work is quite well-known (and quite good)....
