[twenty twenty-four day one six eight]: what ISN’T embodied AI?

The Embodied AI Workshop is coming up this Tuesday, starting at 8:50am, and I am busy procrastinating on my presentation(s) by trying to finish all the OTHER things which need to be done prior to the workshop.

One of the questions my talk raises is what ISN'T embodied AI. And the simplest way I can describe it is that if you don't have to interact with an environment, it isn't embodied.

Figuring out that the golden object on the left and the void on the right is a tremendously complex problem, solved by techniques like CNNs and their variants Inception and ResNet.

But it's a static problem. Recognizing things in the image doesn't change things in the image. But in the real world, you cannot observe things without affecting them.

This is a fundamental principle that goes all the way down to quantum mechanics. Functionally, we can ignore it for certain problems, but we can never make it go away.

So, classical non-interactive learning is an abstraction. If you have a function which goes from image to cat, and the cat can't whap you back for getting up in its bidnes, it isn't embodied.

[drawing every day post ninety-eight]: foot bones

A comparison of hand and foot bones from Goldman. Interestingly, the big toe and thumb both seem to have lost one bone compared to the other fingers / toes. I wonder whether that happened as an evolutionary convergence, or whether they're controlled by the same homeobox or something and were both lost at the same time.

Did I get that word right? Huh, homeobox is the right concept. But, strangely, I remember last thinking about it in a place which I thought was a dream place - a road leading to a bookstore - but now I recall several visits to that bookstore, including a visit to a nearby mall to eat. Huh. I wonder if that was real.

Drawing (and reminiscing) every day.
