Exploring the linguistic landscape: the case of the ‘Golden Triangle’ in the Algarve, Portugal

Studies of the linguistic landscape (LL) are concerned with language in its written form, in the public sphere; language that is visible to all through texts such as billboards and other public signs. The LL is such a taken-for-granted part of our everyday experience that its importance as a form of social practice is often overlooked. Taking a mixed methods approach to the case of the linguistic landscape of the ‘Golden Triangle’, an area of tourist resorts which is gradually becoming a residential area in the Algarve, Portugal, I suggest that the discursive construction of a place is partly achieved through the highly visible texts of the LL which may also impact upon the discursive construction of the collective identities of those who inhabit the place.

Fuzzy rule extraction from input/output data

Several alternative approaches have been discussed: Levenberg-Marquardt - no satisfactory convergence speed + local minimum, Bacterial algorithm - problems with large dimensionality (speed), Clustering - no safe criterion for number of clusters + dimentionality problem.
