Researchers have developed a novel polynomial activation function, f(z) = z + λz^3, which can be clamped and projected onto the unit sphere. This activation function allows deep neural networks to train effectively up to one hundred layers on the MNIST dataset without requiring additional normalization techniques. The study also demonstrates that the loss surface of networks utilizing this activation can be solved exactly at a smaller scale, providing insights into how to design, initialize, and train deeper networks.
