Problem 6: Identifiability of Neural Network Parameters Statement: Investigate the conditions under which the parameters (weights and biases) of a neural network are identifiable, meaning that different parameter settings do not produce the same function. Provide a proof outlining necessary and sufficient conditions for identifiability in multi-layer perceptrons. Key Points for the Proof: • Explore the role of activation functions in parameter identifiability. Examine the impact of network architecture (e.g., number of layers, neurons per layer) on identifiability. • Address permutation symmetries and scaling ambiguities inherent in neural network parameters. Establish conditions that eliminate these ambiguities to achieve identifiability.
