AIGradient descent is an optimization algorithm widely used in machine learning to minimize a loss function, which is a measure of how well a model’s predictions match the actual outcomes.
In the gradient descent process, the model iteratively adjusts its parameters (its weights and biases) to reduce the loss.
The parameters are adjusted based on the gradient, or partial derivatives, of the loss function with respect to each parameter. The gradient points in the direction of the steepest increase in the loss function, so to minimize the loss, we move the parameters in the opposite direction (why negative gradients are used).
By repeatedly subtracting the gradient step-by-step, gradient descent guides the parameters toward values that ideally correspond to the lowest possible loss, improving the model’s performance over time.
