Em relacao a duplicacao da BR-386, uma das liderancas da Terra Indigena Jama Ty Tanh, Maria Antonia Soares, partindo da concepcao de territorio alargado, decidiu chamar as liderancas de outras Terras Indigenas, igualmente situadas em contextos urbanos nas cidades de Lajeado, Porto Alegre, Sao Leopoldo e Farroupilha, para "lutar" pelos direitos indigenas.

However, as we can observe, the hyperbolic tangent (tanh) transfer function performed much worse in terms of the maximal error--up to 14 meters.
Here, the NN1 sub network is a feed forward neural network with one hidden layer with p neurons of hyperbolic tangent (tanh) activation function and an output layer of one neuron with linear activation function.
