Before revision:  Our analysis of this model's learning dynamics reveals that the convergence rate of its parameters is exponentially faster along directions corresponding to the larger principal components of the data, at a rate governed by the singular values.
After revision:  Our asymptotic analysis, assuming that the hidden layers are wide enough, reveals that the convergence rate of its parameters is exponentially faster along directions corresponding to the larger principal components of the data, at a rate governed by the singular values.
