Description: Variable learning rates are a technique used in training machine learning models, where the learning rate is dynamically adjusted throughout the training process. This technique aims to improve the model’s convergence, allowing the optimization algorithm to adapt to different phases of learning. At the beginning of training, a higher learning rate can be beneficial for effectively exploring the solution space, while a lower rate in later stages can help refine the model and avoid oscillations in convergence. There are various strategies to implement variable learning rates, such as reducing the learning rate based on the number of epochs, using techniques like ‘learning rate scheduling’ or ‘cyclical learning rates’, which alternate between high and low rates. This adaptability not only improves training efficiency but can also lead to better results in terms of accuracy and model generalization. In the context of machine learning frameworks, these techniques are easily implementable thanks to built-in tools and functions that allow for straightforward and effective learning rate adjustments.
