吴恩达的Improving Deep Neural Networks课程的第二节对momentum方法有比较细致的描述,momentum被理解为一种对之前步骤中计算的梯度的加权平均,且越早的步的权重越小(指数递减)。 Exponentially weighted average 方法对自变量接近0处的函数值的预测不准,因此往往需要使用bias correction项来弥补这一点。Adam算法中也使用了...

Overall, the approach opens up new avenues to attack problems associated with deep learning, such as trapping in slow manifolds and inapplicability of gradient-based methods for discrete trainable variables. 展开 关键词: deep learning method of successive approximations optimal control pontryagin's ...
One can see a deep architecture as a kind of factorization. Most randomly chosen functions can’t be represented efficiently, whether with a deep or a shallow architecture. But many that can be represented efficiently with a deep architecture cannot be represented efficiently with a shallow one (...

Perceptrons: Early Deep Learning Algorithms One of the earliest supervised training algorithms is that of the perceptron, a basic neural network building block. Say we have n points in the plane, labeled ‘0’ and ‘1’. We’re given a new point and we want to guess its label (this is...
deep reinforcement learning agent, AlphaDev, to play this game. AlphaDev discovered small sorting algorithms from scratch that outperformed previously known human benchmarks. These algorithms have been integrated into the LLVM standard C++ sort library3. This change to this part of the sort library...
