  CONCEPT OF COMPUTATION Input/AntecedentOutput/Consequent y=f(x) is called a mapping function f= fornval method or an algorithm to solve a problem Computing y=f(x) Control action
• 7.
  IMPORTANT CHARACTERISTICS OFSOFT COMPUTING • Should provide precise solution. • Control action should unambiguous and accurate. • Suitable for problem, which is easy to model mathematically.
• 8.
  CHARACTERISTICS OF SOFTCOMPUTING • It does not required any mathematical modeling of problem solving. • It may not yield the precise solution. • Algorithms are adaptive (i.e., it can adjust to the change of dynamic environment). • Use some biological inspired methodologies such as genetics, evolution, ant’s behaviors ,particles swarming ,human nervous system , etc.

  HOW SOFT COMPUTING? Howa doctor treats his patient? • Doctor asks the patient about suffering. • Doctor find the symptoms of diseases. • Doctor prescribed tests and medicines.  This is exactly the way fuzzy logic works. • Symptoms are correlated with diseases with uncertainty. • Doctor prescribes tests/medicines fuzzily.
• 11.
  DIFFERENCE BETWEEN HARDAND SOFT COMPUTING Hard Computing • It requires a precisely stated analytical model and often a set of computation time. • It is based on binary logic, crisp system, neural analysis and crisp software. • It has the characteristics of precision and categoricity • Deterministic • Requires exact input data • Strictly sequential • Produces precise answer Soft Computing • It is tolerant of imprecision uncertainty, partial truth and approximation. • It is based on fuzzy logic, neural networks, probabilistic reasoning etc. • It has the characteristics of approximation and disposition ability. • Stochastics.(random probability distribution or pattern that may be analyzed statically) • Can deal with ambiguous and noisy data • Parallel computations • Yields approximation answer
