Deep Xi neural networks are trained using a stochastic gradient descent optimization algorithm.
Xi rate is a hyperparameter that controls how much the model changes in response to estimation errors each time the model weights are updated. Choosing Xi a learning rate is challenging because a value that is too small can lead to a training process that is too long and can get bogged down, while a value that is too large can lead to a Xi of the suboptimal weight set too quickly or an unstable training process.
When configuring a neural network, the Xi rate is probably the most important hyperparameter. Therefore, it is important to understand how to study the impact of learning Xi Xi rate on model performance and to build an intuition about the dynamics of learning rate on model behavior.
The amount by which the weights are updated during training is called the step size or "learning rate Xi rate." Specifically, Xi rate is a configurable hyperparameter used in neural network training with a small positive value, typically at 00 to 10.
The learning rate Xi control how quickly the model adapts to the problem. Since there is a smaller change in the weights for each update, a smaller Xi learning rate requires more training cycles, while a larger learning Xi rate results in rapid changes and requires fewer training cycles.
Too large a Xi rate can cause the model to converge too quickly to a suboptimal solution, while too small a Xi rate can cause the process to get bogged down.
Momentum can smooth the training of Xi algorithms, which in turn accelerates the training process.
In all cases where momentum is used, the accuracy of the model appears to be more stable on retaining the test dataset, exhibiting less volatility over the training period.
