An Extended Spiking Neural P System for Fuzzy Knowledge Representation
نویسندگان
چکیده
In order to extend capability of spiking neural P systems (SN P systems) to represent fuzzy knowledge and further to process fuzzy information, we propose an extended spiking neural P system in this paper, called fuzzy spiking neural P system (FSN P system). In the FSN P system, two types of neurons (fuzzy proposition neuron and fuzzy rule neuron), certain factor and new spiking rule are considered, and content of neuron is fuzzy number instead of natural number (the number of spikes) in SN P systems. Due to graphical nature and advantages of SN P systems, the FSN P system is especially suitable to model fuzzy production rules in a rule-based system. An example is used to illustrate fuzzy reasoning process based on the FSN P system. Due to distributed and parallel computing and dynamical firing characteristics of FSN P system, it can exhibit potential advantages on fuzzy reasoning. In addition, we compare the FSN P system with other methods on fuzzy knowledge representation and fuzzy reasoning.

Adaptive fuzzy spiking neural P systems for fuzzy inference and learning
Spiking neural P systems (in short, SN P systems) and their variants, including fuzzy spiking neural P systems (in short, FSN P systems), generally lack learning ability so far. Aiming at this problem, a class of modified FSN P systems are proposed in this paper, called adaptive fuzzy spiking neural P systems (in short, AFSN P systems). The AFSN P systems not only can model weighted fuzzy produ...

Spiking neural P systems (SN P systems) have been well established as a novel class of distributed parallel computing models. Some features that SN P systems possess are attractive to fault diagnosis. However, handling fuzzy diagnosis knowledge and reasoning is required for many fault diagnosis applications. The lack of ability is a major problem of existing SN P systemswhen applying them to th...

متن کاملA boundary between universality and non-universality in spiking neural P systems
In this work we offer a significant improvement on the previous smallest spiking neural P systems and solve the problem of finding the smallest possible extended spiking neural P system. P˘ aun and P˘ aun [15] gave a universal spiking neural P system with 84 neurons and another that has extended rules with 49 neurons. Subsequently, Zhang et al. [18] reduced the number of neurons used to give un...
