DEFINITION
Weight initialization means assigning starting numerical values to the weights in a neural network. It determines how information flows through the network. A weight represents how much influence each input has on the model’s prediction.
Done correctly, weight initialization allows a neural network to learn well. Common methods such as Xavier initialization and He initialization suit different activation functions.
