I'm going to need some clarification on the first sentence in the last

Surely the comment about "no symbolic calculation in a neural network"
refers to the abstract data type, rather than the machine-implementation?

Even working at the abstract data-type level, that comment is inobvious.
I'm going to need to know how to reframe your clarification to obviate
the "symbolic calculation" from the "some patterns get more weight than

I have no problems with the last sentence.
