Reflection / ๋ฐ˜์ถ”

I originally planned the mobile as a piece on metacognition, as it apparently is. Then I was about to accompany it with an essay about how we deliberate and reach a decision, which I studied during my PhD.

But while I was making it, I also realized that I had ideas like this, and others, from when I was little. I felt like I’ve only made it now because now I have more experience executing such ideas.

In that sense, the mobile could be also about growth: a larger self looking back on the little selves. Indeed, metacognition, or evaluation of one’s own thinking, can be one way for learning and growth for humans and machines. For example, if you were sure you would be invited to a friend’s birthday and if you were not, you would wonder about the reason and might learn more about what happened to the friend or to your friendship. That’s different from when you were unsure about getting the invitation to begin with, in which case being not invited wouldn’t mean much.ย Therefore, the sense of being sure, or confidence, is a form of metacognition that can help learning. Machines use confidence to learn as well: agreement between the graded sense of confidence and the all-or-none outcomes can beย mathematically expressed as “cross entropy“, which is a standard measureย used in training machines.

Back to the mobile, I debated whether to use wires or paper, but chose paper because each figure is planar. I glued several sheets together to reinforce them. If someone wants it in a more permanent form, I’d like to try 3D printing it.
