摘要
We present an algorithm for fast stochastic gradient descent that uses a nonlinear adaptive momentum scheme tea optimize the late time convergence rate. The algorithm makes effective use of curvature information, requires only O(n) storage and computation, and delivers convergence rates close to the theoretical optimum. We demonstrate the technique on linear and large nonlinear back-prop networks.
