About Fuzzy Logic

Since its introduction nearly 30 years ago, fuzzy logic has established a place in engineering, proving to be especially useful in enabling designers and researchers to model complex, nonlinear systems quickly and effectively. Implemented most commonly in control system design, fuzzy logic-based systems can be found in a rapidly growing number of consumer appliances (from dishwashers to video cameras), as well as in automobile engines and transmissions and industrial equipment. The intuitive nature of the fuzzy-based system design saves engineers time and reduces costs by shortening product development cycles and making system maintenance and adjustments easier.

Also present in an ever broadening range of applications, the use of fuzzy logic for creating decision-support and expert systems has grown in popularity among management and financial decision-modeling experts. Still others are putting it to work in pattern recognition, economics, data analysis, and other areas that involve a high level of uncertainty, complexity, or nonlinearity.

MathOptimizer is a native Mathematica software product that enables the global and local (numerical) solution of a general class of nonlinear optimization problems defined by a finite number of real-valued, continuous functions over a finite n-dimensional interval region. Formally, the model type considered is

min f(x) (scalar objective function)
g(x) <= 0 (set of inequality constraint functions)
h(x) = 0 (set of equality constraint functions)
xl <= x <= xu (finite vector bound constraints)

The primary emphasis is placed upon dense, highly nonlinear systems, including those that have a - typically unknown - number of local optima.

Nonlinear and global optimization problems are ubiquitous in the sciences, engineering, and economics. Several prominent examples are systems of nonlinear equations and inequalities, nonlinear regression, forecasting models, data classification, minimal energy models, various packing problems, risk management and other stochastic decision problems, and the design and operation of 'black box' engineering systems (possibly defined by a complicated, numerically intensive procedure).

You can transform your data to a host of wavelet bases, wavelet packet bases, or local trigonometric bases and do inverse transforms in one and two dimensions. Then view the transform in time-frequency space, selecting different bases and boundary conditions. Data compression and denoising are surprisingly simple procedures with Wavelet Explorer's built-in functions.

In addition to its impressive collection of powerful analysis and visualization tools, Wavelet Explorer is an excellent interactive tutorial for those who are new to wavelet theory. Clear examples start with the basics about wavelets and how to explore wavelet properties, then demonstrate how you can use the system to apply wavelet analysis techniques in your field.
