WebOct 14, 2024 · Gradient descent and stochastic gradient descent can be applied to any differentiable loss function irrespective of whether it is convex or non-convex. The "differentiable" requirement ensures that trainable parameters receive gradients that point in a direction that decreases the loss over time.
