About "point-wise activation value"

[haofuly]

Hi, good work and congratulations.
I am not sure what's the definition of "point-wise activation value" in Figure 5 and 6. In my opinion, it may indicate a point's importance or the model's concentration on this point. Can you give a reference about it?
Thanks a lot.
