Software. The neural networks were made with matlab 2011b and the neural network toolbox Version 7.0.2 for the first example and with matlab R2015b and the neural network toolbox Version 8.4 for the second example. The virtual T-maze paradigm was designed with a freely available game ...
where W is the set of all weights of the neural network and |·||·| represents the absolute value function. The regularization term in Equation (1) is defined as the 2-norm (squared norm) of the network weights. 𝐿2L2 regularization does not have the sparsity property, but it has ...
