As the name implies, we use random matrices to randomly initialize the weights, with the elements of those matrices sampled from some probability distribution with a small standard deviation and zero mean. The main issue with this method is that it can result in vanishing gradients.

Constructing a dictionary is defined as follows: the intercepted training sample images are column vectorized and spliced into a dictionary. The eigenvectors are subjected to dimensionality reduction. Random matrices are employed to randomly project vectors to reduce computational complexity.
