A feedforward neural network with random weights (RW-FFNN) uses a randomized feature map layer. This randomization enables the optimization problem to be replaced by a standard linear least-squares problem. which offers a major advantage in terms of training speed. An extreme learning machine (ELM) is a well-known RW-FFNN that can be implemented as a single-hidden-layer feedforward ne... https://citylocers.shop/product-category/options_hidden_product/
