📈Gradient descent is an efficient technique for optimizing functions on large datasets.
🗻Gradient descent treats the function as a mountain range and tries to find the maximum or minimum point.
🔎In gradient descent, you start at a point and iteratively move in the direction of the steepest gradient.
💡The gradient vector points orthogonally to the contour curves of the function.
🚩The step size in gradient descent can be adjusted to balance convergence speed and accuracy.
What is the purpose of gradient descent?
—The purpose of gradient descent is to optimize functions by finding their local maximums or minimums.
When is gradient descent particularly useful?
—Gradient descent is particularly useful for optimizing functions on large datasets.
How does gradient descent work?
—Gradient descent starts at a point and iteratively moves in the direction of the steepest gradient to find the maximum or minimum point.
What is the role of the gradient vector in gradient descent?
—The gradient vector points orthogonally to the contour curves of the function and helps determine the direction of optimization.
Can the step size in gradient descent be adjusted?
—Yes, the step size in gradient descent can be adjusted to balance convergence speed and accuracy.
