New research details gradient descent dynamics in simplified neural networks

A new paper published on arXiv details the complex dynamics of gradient descent in a simplified neural network model. Researchers analyzed a two-neuron Rectified Linear Unit (ReLU) network trained with gradient flow, revealing that the learning process involves neurons initially converging towards a central point before specializing. The study characterizes the loss landscape, identifying critical points as either global minima or saddles, and tracks the trajectory of the gradient flow to explain this multi-phase symmetry-breaking behavior.
