This is an example of a deep feedforward network, with ϕ \phi ϕ defining a hidden layer. This approach is the only one of the three that gives up on the convexity of the training problem, but the benefits outweigh the harms. In this approach, we parametrize the representation as ...
Xavier Normal:wi,j∼N(0,2nin+nout) Xavier Uniform:wi,j∼U(−6nin+nout,6nin+nout) He初始化: 条件:正向传播时激活值方差保持不变,反向传播时梯度的方差保持不变.适用ReLU.(个人理解因为ReLU在小于零部分截断,所以方差近似减小1/2,所以要把这个部分乘回来) He Normal:w_{i,j} \sim \mathca...
When we use a feedforward neural network to accept an inputx xxand produce an outputy ^ \hat{\boldsymbol{y}}y^, information flows forward through the network. The inputsx \boldsymbol{x}xprovide the initial information that then propagates up to the hidden units at each layer and fi...
