::Biology Suggests New Forms of Deep Learning in Reccurent Networks of Spiking Neurons
* topics
** computational units that boost temporal processing capabilities
** powerfull
* backpropagation through time(BPTT) by e-prop
** cur. replace by feed forward connections
** proposed. e-prop, there is no transmission of error signals backwards in time or space
*** an abundance of error- and learning signals in the brain. microcircuitry of performance monitoring. Nature 2019 - https://www.biorxiv.org/content/10.1101/187989v2
*** backwards propagation of erros is replaed by augmented forward computation
