Week – 3 Lesson Quiz of Launching into Machine Learning

Gradient descent is an optimization algorithm used to maximize some function by iteratively moving in the direction of steepest descent as defined by the negative of the gradient. In machine learning, we use gradient descent to update the parameters of our model.

Gradient descent is an optimization algorithm used to minimize some function by iteratively moving in the direction of steepest descent as defined by the negative of the gradient. In machine learning, we use gradient descent to update the parameters of our model.

In machine learning, we use gradient descent to determine if our model labels needs to be de-optimized.

All of the above

Batch gradient descent, also called vanilla gradient descent, calculates the error for each example within the training dataset, but only before all training examples have been evaluated does the model get updated.

Batch gradient descent, also called vanilla gradient descent, calculates the gain for each example within the training dataset, but only before all training examples have been evaluated does the model get updated. This whole process is like a cycle and it’s called a training epoch.
