WebMar 1, 2024 · The untrained student network has a largely dissimilar pattern of weights to the teacher network, while the trained student network has a very similar pattern to the teacher. Therefore, training the student network on the input-output examples from the teacher allowed us to infer the connectivity between the layers in our ground truth. WebWe still know very little about the properties of these loss surfaces. New discoveries are being made, showing topological behaviour that is highly distinct to neural networks.
