โฆ Synopsis
A practical problem in the identiยฎcation of fuzzy systems from data, is the design and the tuning of the membership functions. We demonstrate that if the data is properly transformed before the identiยฎcation process, the resulting fuzzy model can be improved to the point it may not need a further tuning. The signiยฎcance of the data transform can be validated using statistical methods. The method is demonstrated on a time series prediction problem, using the BoxยฑCox transform.

## Abstract Identifying the underlying dynamics of chemical process systems from experimental data is complicated, owing to a mixture of influences that cause erratic fluctuations in the time series. These influences can be notoriously difficult to disentangle. The development of process models is
A fuzzy model with an adaptive learning rule is proposed to approximate a class of nonlinear systems. The proposed adaptive learning rule uses the concept of terminal attractors and guarantees that the identification is stable and fast convergence in finite time. Another subject of this paper is to
