Solution
The correct answer is b. The process of minimizing the error between the predicted output and the actual output.
Here's a step-by-step explanation:
-
Gradient Descent is an optimization algorithm used in machine learning and deep learning to minimize the cost function.
-
The cost function measures the difference between the predicted output of the model and the actual output. The goal is to minimize this difference to make the model as accurate as possible.
-
In the context of the backpropagation algorithm, which is used in training neural networks, gradient descent is used to adjust the weights and biases of the network in order to minimize the cost function.
-
This is done by calculating the gradient of the cost function with respect to the weights and biases (i.e., the rate of change of the cost function at the current point), and then adjusting the weights and biases in the opposite direction of the gradient. This is why it's called "gradient descent" - because you're "descending" down the cost function in the direction of the steepest gradient.
-
This process is repeated iteratively until the cost function is minimized to an acceptable level, at which point the model is considered to be adequately trained.
