Are these facial expressions designed from experience?

[Young-Chin]

In Expression Edit Node, there are some useful expressions, like "smile", combined with a few key points. My question is that
1, how did you make these expressions? Just by trying？
2, Is there any graph showing the key points related to a human face?

I'm also interested in how the expression math works. Looking at the LivePortrait code, they have some different parameters like lip_variation_zero, lip_variation_one, ..., lip_variation_three, smile, blink, etc. Many of these are the same here but the lip ones especially are a bit different.

I also found it, actually not only the math expression, the detail in these two work is also different, such as the detector, and the pipeline to deal different expression and head move.
