Visualization of the structure, weights, and biases of one of the most successful trained ANNs from DeVries et al (2017). The colors of the connections between neurons encode the magnitude and sign (red positive, blue negative) of each individual weight, while the colors of the neurons represent the sign and magnitude of the bias associated with each neuron. The information contained in this visualization (ANN structure, weights, and biases) is, in some sense, a new and compact representation of viscoelastic physics – image courtesy: B. Meade
