The method for obtaining the fuzzy estimates of regression parameters with the help of “Resolution Identity” in fuzzy sets theory is proposed. The -level least-squares estimates can be obtained from the usual linear regression model by using the -level real-valued data of the corresponding fuzzy input and output data. The membership functions of fuzzy estimates of regression parameters will be ...

This paper investigates the relations between the least-squares approximation techniques and the Fuzzy Transform. Assuming that the function f : R → R underlying a discrete data set D := {(xi, f(xi))}i=1 has been computed with interpolating or least-squares constraints, we prove that the Discrete Fuzzy Transform of the sets {f(xi)}i=1 and {f(xi)}i=1 is the same. This result shows that the Discr...

Hand gestures play an important role in communication between people during their daily lives. But the extensive use of hand gestures as a mean of communication can be found in sign languages. Sign language is the basic communication method between deaf people. A translator is usually needed when an ordinary person wants to communicate with a deaf one. The work presented in this paper aims at d...

Product planning is one of four important processes in new product development (NPD) using quality function deployment (QFD), which is a widely used customer-driven approach. In our opinion, the first problem to be solved is how to incorporate both qualitative and quantitative information regarding relationships between customer requirements (CRs) and engineering characteristics (ECs) as well a...
