My "machine vision" textbook from | college has near zero overlap with the subjects listed in this | blog post, except for face and object recognition as goals, but | the techniques taught for object and face recognition today are | different from what was taught not so long ago. Seems like CNNs | really flipped everything and that nobody starts off with Sobol | operators or Medial Axes or Hough Transforms anymore. Most of | computer graphics and computer science in general is still | building on foundations from thirty, fifty, and seventy years | ago, but it seems like vision has changed more dramatically than | most other sub-field of CS. | mistrial9 wrote: | at Berkeley I studied multiple papers by students of The Mighty | Malik(tm); as said, they may not appear to be aging well, but | the topic is far from exhausted. | | https://people.eecs.berkeley.edu/~malik/ | ramacastro wrote: | Yes definitely, I had the same experience in college a couple | of years ago, the AI course was about "expert systems" and that | kind of old symbolic AI. No neural nets at all. But, | interestingly enough I think neural nets will likely be | combined with something like symbolic methods when we finally | build AGI, mainly for reasoning tasks. | uniqueuid wrote: | Absolutely, except - when you get a bunch of embeddings out of | your CNN, there will still be a lot of vector math to do | anything sensible with it. | sjroot wrote: | When I see posts like these, I immediately go to the company's | homepage to see what they're trying to sell. | | One thing that stuck out to me was the "Our technology partners" | section. Is Theos actually "partnering" with companies like | Google, Meta, Nvidia, OpenAI, etc, on anything? Or is Theos just | using technology from these companies? If it is the latter, this | seems very misleading. | fxtentacle wrote: | Agree, they seem pretty happy to claim ownership. "All of these | examples can be made possible thanks to Theos." | | Didn't you just show me DALLE2 by OpenAI? | uniqueuid wrote: | CV is such a huge field with an incredible breadth of goals, | approaches and basic techniques - this post doesn't do it justice | at all. ___________________________________________________________________ (page generated 2022-07-03 23:00 UTC)
