Connectionists: Scientific Integrity, the 2021 Turing Lecture, etc.

Thu Nov 4 12:45:58 EDT 2021

Lastly Feedforward methods are predominant in a large part because they
have financial backing from large companies with advertising and clout like
Google and the self-driving craze that never fully materialized.

Feedforward methods are not fully connectionist unless rehearsal for
learning is implemented with neurons.  That means storing all patterns,
mixing them randomly and then presenting to a network to learn.  As far as
I know, no one is doing this in the community, so feedforward methods are
only partially connectionist.  By allowing popularity to predominate and
choking off funds and presentation of alternatives we are cheating
ourselves from pursuing other more rigorous brain-like methods.

Sincerely,
-Tsvi
