There are many terms that are defined differently in different fields... and unfortunately things are not as simple as looking them up in a dictionary. <div><br></div><div>For example the term recurrent connections have different meanings in the computational neuroscience, neural networks, and cognitive psychology communities.</div><div>In neural networks recurrent means an output used back as an input within a paradigm of delayed inputs. It is a method of representing time or sequences. Often recurrent connections in neural networks are confused with feedback back to the same inputs which are actually never used in neural networks because it forms an infinite loop and is not possible to rewind in order to generate an error signal.</div><div>In computational neuroscience recurrent connections are used to describe lateral connections.</div><div>In cognitive psychology the term re-entrant connections are used to describe feedback back to the same inputs.</div><div> </div><div>I believe in order to truly appreciate "brain-like" ideas, members of this group need to familiarize themselves with these brain-focused fields. For example in cognitive psychology there is a rich literature on salience (which again is a bit different from salience in the neural network community). Salience is a dynamic process which determines how well a certain input or input feature is processed. Salience changes in the brain depending on what other inputs or features are concurrently present or what the person is instructed to focus on. There is very little appreciation, integration or implementation of these findings in feedforward networks, yet salience plays a factor in every recognition decision and modality including smell and touch.</div><div><br></div><div>Consciousness is a particularly problematic minefield which also adds in philosophy, metaphysics and subjectivity into the mix.</div><div><br></div><div>Juyang, I think we both agree about the basics: the need for more realistic real world recognition and to move beyond the rehearsal limitations of neural networks. I believe scientists not seeing eye-to-eye with each other and other members of the community is in no small part due to these terms.</div><div><br></div><div>Sincerely,</div><div>-Tsvi</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 15, 2022 at 9:54 AM Juyang Weng <<a href="mailto:juyang.weng@gmail.com" target="_blank">juyang.weng@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Dear Tsvi,<br>You wrote "A huge part of the problem in any discussion about consciousness is there isn't even a clear definition of consciousness". <br>Look at the 5 level definition of consciousness:<br><a href="https://www.merriam-webster.com/dictionary/consciousness" target="_blank">https://www.merriam-webster.com/dictionary/consciousness</a><br><br></div><div>You wrote: "So consciousness is not necessary or sufficient for complex thoughts or behavior."<br>I was thinking that way too, until recently. <br>I found consciousness IS REQUIRED for even learning basic intelligence. </div><div>To put it in a short way so that people on this list can benefit:<br>The motors (as context/actions) in the brain require consciousness in order to learn correctly in the physical world.
