       | One of the most striking things about intro computer vision
       | explanations & courses today is how completely things have
       | changed in the last 20 years. 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.

         | 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.

         | 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.

         | 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.

       | 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.

         | 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?

       | 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.
