Description: The ‘Learning Rate Decay’ is a technique used in the training of machine learning models, especially in the context of deep learning. This strategy involves gradually reducing the learning rate as the training process progresses. The learning rate is a crucial hyperparameter that determines the size of the steps the model takes when updating its parameters in response to errors made. A controlled decrease in this rate allows the model to adjust more precisely to the data, avoiding oscillations and improving convergence towards an optimal minimum. This technique is particularly relevant in scenarios where data is heterogeneous or distributed, such as in federated learning, where multiple devices collaborate to train a model without sharing sensitive data. By decreasing the learning rate, it becomes easier for the model to adapt to variations in data coming from different sources, resulting in a more robust and generalizable performance. In summary, ‘Learning Rate Decay’ is a fundamental strategy for optimizing the training process in machine learning models, enhancing their convergence capability and adaptability to complex environments.
