A corrigendum on

Generating functionals for computational intelligence: the Fisher information as an objective function for self-limiting Hebbian learning rules
by Echeveste, R., and Gros, C. (2014). Front. Robot. AI 1:1. doi: 10.3389/frobt.2014.00001

In formula (10) of (Echeveste and Gros, 2014) the Fisher information with respect to the synaptic flux was formulated formally as an integral over the postsynaptic activity y, without stating explicitly that the postsynaptic activity y = y(y) is actually a function of the N_w presynaptic activities $y = (y_{1}, \dots, y_{N_{w}}) .$ The correct version of equation (10) is hence

F_{w} = {\int (\sum_{j = 1}^{N_{w}} w_{j} \frac{\partial}{\partial w_{j}} \ln (p (y (y)))}^{2} \times p (y) d y .

The functional dependence of the postsynaptic y on the presynaptic y was implicitly used in equation (12) and in the derivation of the synaptic plasticity rules, but otherwise not explicitly stated.
