报告摘要:

The feedforward neural networks have been widely used in many fields. However, there exist singular behaviors in the learning processes, such as the learning process often becomes very slow, is easy to converge to the local minima, and the learning dynamics sometimes trap in the so-called plateaus. In this report, the theoretical and numerical analysis near singularities in typical feedforward neural networks, such as the multilayer perceptrons and RBF networks, are investigated and the mechanism of these singular behaviors is introduced.
