- 11. Hard Computing • LAZ(Lotfi Aliasker Zadeh) in 1996. • As per him, hard computing gives • Precise results • Steps are unambiguous • Control action is formally defined by a mathematical model/algo. 11
- 12. Examples of Hard Computing •Solving numerical problems such as roots of a polynomial, integration, differentiation etc. • Searching and sorting algorithms give precise results with defined algo. • Computational geometry problem (Shortest tour in a graph). 12
- 13. 13 Introduction to SoftComputing Soft Computing is the collection of computational techniques in Computer Science, AI, Machine learning and some engineering disciplines which attempt to study, model and analyze very complex phenomenon – those for which conventional methods have not yielded lost cost, analytic and complete solutions. Some of it’s principle components includes: • Neural Network(NN) • Fuzzy Logic(FL) • Genetic Algorithm(GA)
- 14. SOFT COMPUTING (SC) SCwas coined by LAZ. Lotfi A. Zadeh (Inventor of fuzzy logic) discovered soft computing. He describes it as follows: “Soft computing is a collection of methodologies that aim to exploit the tolerance of imprecision and uncertainty to achieve tractability, robustness & low solution cost. “ Role model of SC is human brain.

- 30. Transportation • Soft Computingis applicable in constructing intelligent vehicles and provide efficient environment to each other i.e. to machines and drivers. • Intelligent vehicle control requires recognition of the driving environment and planning of driving that is easily acceptable for drivers. • The field of transportation deals with passengers, logistics operations, fault diagnosis etc. • Fuzzy Logic and Evolutionary Computing are often used in elevator control systems. 30
- 31. Healthcare • Health careenvironment is very much reliant to on computer technology. • With the advancement in computer technology, the use of Soft Computing methods provide better and advance aids that assists the physician in many cases, rapid identification of diseases and diagnosis in real time. • Soft Computing techniques are used by various medical applications such as Medical Image Registration Using Genetic Algorithm, Machine Learning techniques to solve prognostic problems in medical domain, Artificial Neural Networks in diagnosing cancer and Fuzzy Logic in various diseases 31
- 32. Summary • As thedevelopment of soft computing flourish day by day, the application areas will also be felt increasing in coming years. Soft computing based products are increasing day by day. Majority of such products uses any of the soft computing technique inside the sub systems which are not known to end user. The gist is that, soft computing techniques will become common to various applications and has ability to deal with imprecise problems. 32

Hard computing vsSoft computing Hard Computing Soft computing Precisely stated analytical model required Imprecision is tolerable More Computation time required As it involves intelligent computational steps, computational time required is less It involves binary logic crisp systems and numerical analysis It involves nature inspired systems such as neural networks, fuzzy logic systems and swarm intelligent system. Precision is observed within the computation Approximation is obtained in the computation Imprecision and uncertainity are undesirable properties Tolerance for imprecision and uncertainty is exploited to achieve tractability, lower cost, high Machine intelligence quotient and economy of communication. It produces precise answers It can produce approximate answers
- 37. Hard computing vsSoft computing Hard Computing Soft computing Programs are written which follow standard rules of programming Programs are evolved which require new laws and theories to be created and justified while programming The outcome is deterministic(i.e., Every trial run, the output is same) The outcome is stochastic or random in nature and need not be deterministic It requires exact input data It can deal with ambiguous and noisy input data It strictly follows sequential computations It allows parallel computations
