<p>Yes, Jon good point here, and although there is a through line from Hopfield to Hinton and Sejnowski.. Ie boltzmann machines and onto DL and LLMs<o:p></o:p></p>
<p>Dave of course invented BP, Geoff would always say.. his contribution was to try and talk Dave out of it as it had so many computational problems and could be in no way considered biologically plausible.<o:p></o:p></p>
