     "The neural network defines a prior over the mean `loc` of the data likelihood `obs` which is represented by a normal distribution. For simplicity, the aleatoric uncertainty (`noise`) in the data is assumed to be known. Thanks to PyMC4's model composition support, priors can be defined layer-wise using the `layer` generator function and composed to a neural network as shown in function `model`. During inference, a posterior distribution over the neural network weights is obtained. "
