unlike patent, there are not clear legal rules to protect know how in iranian law, then intellectual property law theories require to afford protection to know haw and its owner. the protection rules may be provided under contractual bases or under law. approaches of legal systems towards the terms and rules of the protection are different. in iranian legal system some protection rules are foun...

DBSCAN is a density-based clustering algorithm. This algorithm clusters data of high density. For finding core objects traditional DBSCAN uses this core object as center core which extends outwards continuously. As core objects are growing, the unprocessed objects which are retained in memory, will occupy a lot of memory and I/O overhead which tends to low efficiency of algorithm. A data mining...

This study proposes a fuzzy neural network (FNN) that can process both fuzzy inputs and outputs. The continuous genetic algorithm (CGA) is employed to enhance its performance. Both the simulation and real-world problem results show that the proposed CGA-based FNN can obtain the relationship between fuzzy inputs and outputs. CGA can not only shorten the training time but also increase the accura...

This paper proposes an Enhanced Particle Swarm Optimization (EPSO) for extracting optimal rule set and tuning membership function for fuzzy logic based classifier model. The standard PSO is more sensitive to premature convergence due to lack of diversity in the swarm and can easily get trapped into local minima when it is used for data classification. To overcome this issue, BLX-α crossover and...

In this paper, based on the our previous researchs about generalized modus ponens with linguistic modifiers for If ... Then rules, we propose generalized If...Then...Else inference rules with linguistic modifiers in linguistic many–valued logic framework with using hedge moving rules for approximate reasoning.

This research examines which method is better for programming rule-based expert systems: IF-THEN rules or decision tables. Thirty undergraduate MIS students served as experimental subjects in an eight week study. After four weeks, subjects wrote decision tables covering cases significantly more consistently than IF-THEN rules (p<.01). After eight weeks, however, subjects wrote IF-THEN rules tha...
