What is Learning Rate?
- Learning rate is a crucial hyperparameter in machine learning that controls the degree of updates on the model's weights.
- Generally, a loss function represents a hyperplane(초평면) in multi-dimensional space characterized by complex curvatures.
- If the weight updates are too large and overshoot the global minimum(the point where the loss function could be minimized), it becomes impossible to find the optimal solution(optimal weights and biases).
- If the learning rate is too high, the weight cahnges can be too large, causing it to overshoot the global minimum.
- When the learning rate is appropriate, weight changes are stable, allowing the model to efficiently reach the global minimum.
- Therefore, it's necessary to adjust the amount of weight updates to avoid missing the global minimum.
