C. Optimization occurs once in any machine learning process
Answer
x
Explanation
Optimization in machine learning is an iterative process that occurs multiple times throughout the training of a model, not just once. The goal of optimization is to minimize the loss function by adjusting the model’s parameters, namely the weights and biases. This process is repeated until the model converges to a satisfactory solution or a predefined stopping criterion is met.
During each iteration, the optimization algorithm, such as gradient descent, computes the gradients of the loss function with respect to the model’s parameters. These gradients indicate the direction in which the parameters should be updated to reduce the loss. The parameters are then adjusted accordingly, and the process is repeated with the updated parameters.
Optimization is a crucial component of machine learning because it enables the model to learn from the training data and improve its performance. Without proper optimization, the model may not be able to effectively capture the underlying patterns in the data, leading to poor generalization and suboptimal results.
Therefore, statements A and B are correct:
A. Optimization is needed to minimize loss
B. Optimization involves tuning the parameters — Weight and Bias
These statements accurately describe the purpose and mechanism of optimization in machine learning.
