1.
2. Soft computing is a field of computer
science which makes use of inexact
solutions for problems which has no
known method to compute an exact
solution
It uses imprecision, uncertainty, partial
truth, and approximation as input
3. It’s aim is to exploit the tolerance for
Approximation, Uncertainty, Imprecision,
and Partial Truth in order to achieve close
resemblance with human like decision
making
The main goal of soft computing is to
develop intelligent machines to provide
solutions to real world problems, which are
not modeled, or too difficult to model
mathematically.
5. Hard computing
Deals with precise values
Accurate output is needed
Useful in critical systems
Soft computing
Deals with assumptions
Accuracy is not necessary
Useful for routine,control, decison making tasks
7. • Founded in 1940
• Artificial neural network mimics the
biological neuron network in function
k
8. An NN, in general, is a highly interconnected
network of a large number of processing
elements called neurons in an architecture
inspired by the brain.
NN Characteristics are:-
Mapping Capabilities / Pattern Association
Generalisation
Robustness
Fault Tolerance
Parallel and High speed information processing
9. • Based on fuzzy set theory and fuzzy logic
• Uses numeric ranges of sets (fuzzy sets )
to measure and represent the logical
evaluations of partially accurate findings
• Most applications in control and decision
making
• Founded by Lofti A Zadeh
13. 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.

14. Models based on human reasoning.
Closer to human thinking and biologically
inspired
Models can be
Linguistic
Comprehensible
Fast when computing
Effective in practice.
15. Heavy industry
Robotic arms, Humanoid robots

17. Soft Computing can be extended to include bio-
informatics aspects.
Fuzzy system can be applied to the construction
of more advanced intelligent industrial systems.
Soft computing is very effective when it’s applied
to real world problems that are not able to
solved by traditional hard computing.
Soft computing enables industrial to be
innovative due to the characteristics of soft
computing: tractability, low cost and high
machine intelligent quotient.
