ðŸ’« Short Summary

Layer normalization is a technique used in neural networks to stabilize and speed up training by normalizing the activation values of every neuron in every layer. It involves subtracting the mean and dividing by the standard deviation of the activation values, and includes learnable parameters gamma and beta. The process ensures more stable and consistent training. The video provides a detailed explanation and coding example of layer normalization in the context of the Transformer neural network architecture.
