Before revision:  Even though several models have been proposed , it remains a challenging task to design RSNNs which use biologically plausible mechanisms . We propose a general probabilistic framework which relies on the principle of maximizing the likelihood for the network to solve the task .
After revision:  Even though several models have been proposed , it remains a challenging task to design RSNNs which use biologically plausible mechanisms capable of solving complex temporal tasks. We use a general probabilistic framework which relies on the principle of maximizing the likelihood for the network to solve the task .
