Description: The fixed learning rate is a crucial parameter in the training of machine learning models, determining the magnitude of adjustments made to the model’s weights at each iteration of the optimization process. Unlike variable learning rates, which can change over time, a fixed learning rate remains constant throughout training. This means that the model makes uniform updates based on the information it receives from the training data. A learning rate that is too high can cause the model not to converge, jumping over the optimal minimum, while a rate that is too low can result in an extremely slow training process and, in some cases, an inability to reach the global minimum. Choosing an appropriate learning rate is essential for the model’s performance, as it directly influences the speed and effectiveness of learning. In practice, it is common to experiment with different learning rate values to find the one that best fits a specific problem, and its proper configuration can be the difference between a successful model and one that fails to generalize well to new data.
