This is why I have tried to drill into junior devs that it is important to take a step back for several minutes before responding to criticism. It's just too easy to fall into the trap of interpreting comments and suggestions on improvement as a personal attack.
Probably, though the artist appeared to draw η (eta) rather than n which could mean they’re using learning rate to compute the bounds of some other value. I’m more curious what y-base log they’re taking and why.
It’s almost like it’s just supposed to look mathy or something.
