Management Information Systems

Notes  Japanese-made products that use fuzzy logic microprocessors comprise auto-focus cameras,
auto-stabilizing, camcorders, energy-efficient air conditioners, self-adjusting washing
machines, and automatic transmissions.

Fill in the blanks:
5. Fuzzy Logic Systems are .................................... systems that can process data that are
incomplete or only partially correct.

6. .................................... is a method of reasoning that resembles human reasoning since it
allows for approximate values and inferences and incomplete data instead of relying only
on Crisp data, such as binary (yes/no) choices.

12.3 Neural Networks Artificial Neural Systems

Neural networks are defined as computing systems modeled on the human brain’s mesh-like
network of interlinked processing elements, known as neurons. Neural networks can be executed
on microcomputers and other computer systems through software packages, which simulate
the actions of a neural network of many processing elements. Specialized neural network
co-processor circuit boards are also obtainable. Special-purpose neural net microprocessor chips
are used in some application areas. Uses comprise:
 Military weapons systems
 Voice recognition
 Check signature verification

 Manufacturing quality control
 Image processing
 Credit risk assessment

 Investment forecasting
 Data mining

Notes Obviously, neural networks are much easier than the human brain (measured to
have more than 100 billion neuron brain cells). Similar to brain, however, such networks
can process many parts of information at the same time and can study to identify patterns
and program themselves to solve associated problems on their own.
