The subgradient method is an optimization technique used to minimize non-differentiable convex functions. While traditional gradient descent is applicable to differentiable functions, many optimization problems involve functions that are not smooth or do not have well-defined gradients everywhere. In such cases, subgradients provide a useful alternative.
