Minimizing Control for Credit Assignment with Strong Feedback [article]

Alexander Meulemans, Matilde Tristany Farinha, Maria R. Cervera, João Sacramento, Benjamin F. Grewe
2022 arXiv   pre-print
Building upon deep feedback control (DFC), a recently proposed credit assignment method, we combine strong feedback influences on neural activity with gradient-based learning and show that this naturally  ...  However, current biologically plausible methods for gradient-based credit assignment in deep neural networks need infinitesimally small feedback signals, which is problematic in biologically realistic  ...  We would like to thank Nicolas Zucchet for his valuable feedback and engaging discussions on the optimization theory aspects of the minimizing control framework; and Aditya Gilra for insightful discussions  ...
