Soft computing is an approach to building computationally intelligent systems that is tolerant to imprecision and uncertainty. It includes techniques like fuzzy logic, neural networks, and evolutionary computation. These techniques were developed to mimic human-like intelligence by accommodating imprecision and exploiting uncertainty. Soft computing is used to build intelligent systems that can learn and adapt to new environments. Neuro-fuzzy systems combine neural networks and fuzzy logic to create adaptive and knowledge-based intelligent systems.
