The output of this phase is the intercept "q" of the optimum line and the corresponding angle "alpha". Then each neuron has threshold c = - q*cos(alpha).}

The dynamics of this network is regularized by adding a term to the energy function that is minimized when the proportion of positive in the network state is roughly the proportion of positives in the labeled part of the network. The parameter "cost" corresponds to the parameter beta  in the equation eta = beta*|tan((alpha - pi/4)*2)| (see Frasca et al. 2013). When the equilibrium state is reached, positive nodes will be predicted as positive for the current task.}
