Agenda
The guiding principle of soft computing is to exploit these tolerance to achieve:-
• Flexibility.• Robustness.• Low Solution Cost.
Principle
Soft computing is the fusion of methodologies designed to model and enable solutions to real world problems, which are not modeled or too difficult to model mathematically.
The aim of soft computing is to exploit the tolerance for imprecision(not-repeatable), uncertainty, approximate reasoning, and partial truth in order to achieve close resemblance with human like decision making.
Soft Computing
Field of computer science which makes use of inexact solutions for problems which has no known method to compute an exact solution.
Problems in whose solutions are unpredictable, uncertain and between 0 and 1.
Fuzzy Logic, Neuro-Computing, Evolutionary and Genetic Computing, and Probabilistic Computing.

Soft Computing
SC = EC + NN + FL
To develop intelligent machines to provide solutions to real world problems, which are not modeled, or too difficult to model mathematically.
Well suited for real world problems where ideal solutions are not there.
Goals of Soft Computing
PROBLEM SOLVING TECHNIQUES
Hard computingDeals with precise values.Accurate output is needed.Useful in critical systems.
Soft computingDeals with assumptions.Accuracy is not necessary.Useful for routine, control, decision making
tasks.
Hard computing Vs. Soft computing
I. Fuzzy Systems. II. Neural Networks. III. Evolutionary Computation. IV. Machine Learning. V. Probabilistic Reasoning.
Techniques in Soft Computing
Machine Learning Pattern recognition
based on training data Classification supervised by instructor.
Unsupervised machine learning is also used where the machine learns from the given data by detecting patterns.

Models based on human reasoning. Closer to human thinking and biologically
inspired. Models can be
i. Linguistic.ii. Fast when computing.iii. Effective in practice.
Advantages of SC
Heavy industry:- Robotic arms, Humanoid robots
Home appliances:- Washing machines, ACs, Refrigerators,
cameras
Automobiles:- Travel Speed Estimation, Sleep Warning
Systems, Driver-less cars
Application of soft computing
