Xavier Initialization in MxNet with Average Magnitude Scaling Factor and Uniform Random Distribution Type The provided code utilizes Xaver initialization method from mxnet library in Python for initializing the model's weights. The Xavier initializer uses a scaling factor that is chosen to prevent overflows when using ReLU activation functions, but the most widely used version of Xavier initializer is one that scales both positive and negative values uniformly. For this problem, we are told that we want to use initializer = mx.
